live view of bottom navigation in design view is not showing icons and the menu resource-CodePudding

[![enter image description here][2]][2]The bottom navigation view is not showing the icons in it, in the live- design view of the android studio as of material io 1.5.0. and I see on my previous projects that in material io 1.3.0 it's working on old but not in the new version.

I am just seeing an empty bottom navigation bar, and nothing on it. I will really appreciate your help in this regard.

here is the code XML:

This problem occurred while using the new material io 1.5.0 library, and it's working fine on 1.3.0.
