Over sensitive button?

Hey all, brand new to fighting games and sticks. I got my Madcatz SE stick today but I seem to have one button (R1) is more sensitive then any of the others. If I try to press hp and mp at the same time often hp will come out first making some moves (ex’s and ultras) kinda annoying to actually hit off. Just having my fingers rest on the keys will have high punch going.

Has anyone got any suggestions on how to fix this?

Edit: I do plan to mod the stick later when I have some more funds but its going to be a month or two, so looking for a short term fix if the button is faulty.
Edit: Played on it some more, the button is definitely more sensitive I can run my finger across the button and it activates where the other buttons need to be pushed down before they react.

Should I just swap one of the 7/8 buttons into that r1 slot?

Thanks.
