Extra space between Collapsing Toolbar Title when expanded

Question

I am facing problem for reducing left spaces of the Collapsible Toolbar Layout title. I want to align the title just below of the back button and I am unable to reduce the space. Thanks in advance. Here is the code.

You forget to add app:layout_scrollFlags="scroll|enterAlways" in CollapsingToolbarLayout & if possible please attach the issue picture because it is easy to understand others
