Can not delete a preview asset from socket

Hi,
In the editor, whan I double click on my skeletal mesh, I see three sockets I added, each socket has a preview asset.

I was never able to delete one preview asset from those sockets.

Is there another way to do this than just click delete on the menu ?

This will be so helpfull…

Just discovered today after two years…
Hold the left mouse button down and press delete on the keyboard.
Not intuitive at all but it works

Thanks a lot, man! It works!

omg. your still a life saver in 2025 xd… little sad from engine side

They broke it during an update and never fixed it, it was selectable in UE 4.19 (I remember this because I installed all the engine versions to test it out
:rofl:)
