onclick firing infinite times

Hello can someone help me understand why this is happening:

When i click a button with onclick (via UI) configured all of the events are firing infinite amount of times till i click again on a different part of the screen or off of the game all together....if i don't it will keep firing the vent over and over again rapidly. Once i click in a seperate area or off of the unity editor / game

The strange thing is that this just started happening out of the blue. I change a script that has nothing to do with the scene that its occurring on. For the sake of just trying to fix it - i removed the 3 lines of code - but not surprisingly it did the same thing
I tried to remove the library and rebuilt - still nope

it seems like its only UI set ONCLICK Event buttons that are having this issue - my scripted onclick listeners do not have this issue at all

thanks for your time!

my next attempt i think it to upgrade or something but i am already on 2021.1.25f1

 

wonky - something to do with the input manager - updated to the new one - no more issues

 

So the onclick seems better but something is still funky with the scroll bar - when i click it its glitchy scrolling up and down sporadically then i click off on another part of the screen and it stops
