'Common UI' widgets do not register a single/double click in 5.5

don’t know if anyone has encountered this problem, but I’m starting to get desperate so hopefully somebody knows.
In 5.5, after turning on ‘Common UI’, I’m not getting a response for double clicks.
This doesn’t seem to be a problem for the rest of the engine, ONLY inside the widgets.
It works everywhere else… but somehow the single/double click just doesn’t register correctly. Tried the controller, mouse… nothing.

Is this a common thing when using ‘Common UI’?
Is it caused because is 5.5?
Has this happened to anyone else… and more importantly, is there a fix?

I would LOVE any tips u guys might have, cause I kinda need buttons inside my widgets to be clickable :slightly_smiling_face:
