Can not open Level Variant Manager

Hello!

I am trying to use LevelVariantSet as to the videos posted changing wheels etc.

when I create a LevelVariantSet name it whatever I want and then double click it NOTHING happens the manager doesn’t open up, no windows open up or anything, I have tried this in 4.24 and 4.25 and it is the same on both version.

i am now stuck and not sure what to do with this and there is no information online for bug’s or error’s on this matter.

in the output window, all I get is… “LogAssetEditorSubsystem: Opening Asset editor for LevelVariantSets /Game/NewSet.NewSet” but then nothing.

Hope someone can help

Thanks
Kev
