8bitdo sf30 pro button "select" : classic id button "109" become "4"

Hi, I’m on shield tv android and since an update of retroarch (I think) I experience a weird behaviour. on my sf30 pro 8bitdo paddle, the “select” button is regonized as id “4” instead of the classic id “109” since the beginning when configuring the buttons. so it breaks all my controller profile. I can change the number on my different files but don’t understand why this button change from id number. all other button as reconized as usual (ex: start as: id 108). is someone as encounter this problem? thanks
