TextInputLayout change width when error occurred

Question

I Have the LinearLayout with two nested TextInputLayout.

When there is no error, then everything is OK. But when an error occurs, the size of the TextInputLayout changes. Tell me please, what am I doing wrong.

<LinearLayout
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:layout_marginLeft="16dp"
      android:layout_marginRight="16dp"
      android:layout_marginTop="40dp"
      android:baselineAligned="false"
      android:orientation="horizontal">

       <android.support.design.widget.TextInputLayout
        android:id="@+id/textInputPower"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginRight="5dp"
        android:layout_weight="1"
        android:orientation="horizontal">

         <EditText
          android:id="@+id/editText3"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:digits=".0123456789"
          android:hint="Мощность (W)"
          android:inputType="numberDecimal"
          android:maxLength="10"
          android:textColor="@color/text_color_nav"
          android:textSize="14sp" />
         </android.support.design.widget.TextInputLayout>

          <android.support.design.widget.TextInputLayout
           android:id="@+id/textInputAmperage"
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:layout_marginLeft="5dp"
           android:layout_weight="1">

            <EditText
             android:id="@+id/editText"
             android:layout_width="match_parent"
             android:layout_height="wrap_content"
             android:digits=".0123456789"
             android:hint="Ток (А)"
             android:inputType="numberDecimal"
             android:maxLength="10"
             android:textColor="@color/text_color_nav"
             android:textSize="14sp" />
            </android.support.design.widget.TextInputLayout>
    </LinearLayout>

Use weight sum for linear layout.

    <LinearLayout android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginLeft="16dp"
    android:layout_marginRight="16dp"
    android:layout_marginTop="40dp"
    android:baselineAligned="false"
    android:weightSum="2"
    android:orientation="horizontal"
    xmlns:android="http://schemas.android.com/apk/res/android">

    <android.support.design.widget.TextInputLayout
        android:id="@+id/textInputPower"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginRight="5dp"
        android:layout_weight="1"
        android:orientation="horizontal">

        <EditText
            android:id="@+id/editText3"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:digits=".0123456789"
            android:hint="Мощность (W)"
            android:inputType="numberDecimal"
            android:maxLength="10"
            android:textColor="@color/text_color_nav"
            android:textSize="14sp" />
    </android.support.design.widget.TextInputLayout>

    <android.support.design.widget.TextInputLayout
        android:id="@+id/textInputAmperage"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="5dp"
        android:layout_weight="1">

        <EditText
            android:id="@+id/editText"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:digits=".0123456789"
            android:hint="Ток (А)"
            android:inputType="numberDecimal"
            android:maxLength="10"
            android:textColor="@color/text_color_nav"
            android:textSize="14sp" />
    </android.support.design.widget.TextInputLayout>
</LinearLayout>
