Some blueprint instances placed in a scene dosen’t change when toggle exposed variables

Hi Unrealers!

I got a parent blueprint actor that is build up to only run in the construction script. For every bit code i made i’ve tested it to make sure it worked before building more. So i’m done with the system now.

The problem is that some of the child blueprints instance i placed in the scene from the start dosen’t work as intended, like: some exposed boolean and floats
dosen’t make the blueprint to change.

BUT some of the other instance of the same blueprint works fine?!

This is what i’ve tried:

• Delete the instances that didn’t work and place an new into the scene

• reseted the placed blueprint instance in the scene to its blueprint default settings

• I’ve deleted the unreal project windows explore folder (saved, intermediate, DerivedDataCache)

And nothing worked, i’m I missing something or is there someone that have an idea of why this is happening?
