I downloaded UE4.10 just to test this, and guess what?
Preview assets were selectable and you were also able to right click and delete them!
At this point, it was personal.
I’ve opened a bug report and linked this thread.
Tested engine versions:
- 4.10.4 - Working
- 4.17.2 - Working
- 4.18.3 - Working
- 4.19.2 - Working

- 4.25.5 - Broken
- 4.26.2 - Broken
- 4.27.2 - Broken

I don’t really know how a feature like this broke and nobody noticed it
