Joy Con pushing random buttons on switch

I have two sets of Joy Cons one that it came with (never had issues with) then We bought a pink and green set.. a while back we started having issues with the joy con randomly pushing buttons on the switch, we thought it was the switch but it never happened with any other controller or the other set of joy con. Well last night I went and bout a brand new set of joycons from Costco and now we are having the same issue that we do with the pink and green set with it pushing random buttons. I mean… these aren’t cheap… I keep googling it and no one seems to have the real same issue. Please sent help!!
