Weird collapsing on inspector

Hello everyone. Recently, I’ve had a weird behavior on my inspector, which happens the most on PlayerInput.


Whenever I click on the plus or minus sign, it immediately collapses the Events menu, therefore I can’t watch and modify it unless unfolding it again. This happens to the others too, though I could not recall which atm.
What’s the problem here I wonder, any help would be appreciated.

Even weirder, when assigning the method for the first time, the method remains selected, but its name doesn’t show, still says ‘No Function’ until I change to the other method.

After using Ctrl+C, Ctrl+V to assign objects, this bug is fixed. I’m not 100% sure, but might it be a fix for later user looking for it.
