Warning "use Modelica.Icons.Package instead" in Modelica code

I meet a warning use Modelica.Icons.Package instead in the Modelica code. it seems I am using a wrong icon so the tool chooses to use Modelica.Icons.Package instead.

So I check the code that showed in the warning message, there is no icon in this component, so why this warning happens?

The following screenshot shows the warning message and the Modelica code of the wrong component.

<h4>Description</h4>
<p>Generic heat transfer model where the heat transfer correlation is replaceable and is compatible with heat-correlations for two-phase correlations.</p>
<h4>Parametrization</h4>
<p>This model is parametrized by it&apos;s geometry and operating point. The operating point and  flow properties are specified as inputs and can therefore be variables that change with time.</p>
<h4>Assumptions</h4>
<ul>
<li>No heat storage</li>
</ul>
