Thanks for filing this.
This is working as intended, since Card in your case have bigger elevation than a TopAppBar.
As you place it in a Column { TopAppBar; ListOfCards }, cards are drawn after the top app bar, and overlap its shadow.
You either need to switch to the Box and compose the TopAppBar after the list of cards Or use Scaffold that handles this order for you Or use Modifier.zIndex (not recommended) to have higher Z index in the top app bar than in the card.

I attached screenshots and created a project on GitHub to easily reproduce this problem:
