Hello friends.i have a weird

Hello friends.i have a weird issue.i have Ableton 11 and a midi keyboard (novation launchkey 25)..in the keyboard,3, particular keys keep playing wrong..it sounds like,instead of playing the note,playing a chord that is a bit out of tune..no matter what synth,no matter what project,I even uninstalled and reinstalled Ableton but still.

I searched a lot for a way to reset keyboard settings but I found nothing.anybody has any idea?thanks in advance !
