Lyra>CommonUI. UCommonActivatableWidgetContainerBase::WidgetList does not get flushed properly?

Hello everyone.

I am currently debugging Lyra, namely CommonUI specific part(Unreal 5.2)
I faced an issue when I open Mainmenu, click NewGame, then select Experience, then exit game, and then repeat the sequence of the steps.
UCommonActivatableWidgetContainerBase::WidgetList does not seem to be emptied correctly:

Has someone seen or can confirm the behaviour?
In the project I am currently working on I fixed it like this:


Could someone approve correctness or maybe there are any other ways to fix it?

Thank you in advance,
