The asset manager will fully reload assets after you remove one or more of them from your game. The number of assets it reloads seems to always be the same number regardless of how big your widget is. So if your asset manager widget is large enough, it will not populate fully. Normally this wouldn’t be much of an issue because you would scroll down in the asset manager and it will automatically load more assets, except that there is no scrollbar if your widget is too large.
In the video below I remove assets from my widget and I am unable to load more assets. This is because my widget is too large. I am trying to scroll down but I can’t. I have to scale the widget down before I can scroll down to load more assets.
I expect my asset manager window to populate fully.
