Sometimes the wrong assets get placed

I only have the Default Assets - 2MTT pack and browsing with the 2M Dungeon Trap Assets tag filter active.

Clicking an assets adds the right one to the place "stack" above the library (not sure how to call that) but actually placing it places the wrong asset.

Note that this only seems to happen with specific assets, notably all the ones in the above tag but also a few other random ones.
