a new issue has came today on my Yocto. The 10th step button is working in a weird way.
I'll try to describe its behavior.
It's lighting on without touching it...And when I press and keep an other step, it lights off. Also pressing on it, it won't turn off... It looks like it's working in a reverse way...
Sometimes it works and behaves in a normal way, sometimes it doesn't.

I thought maybe there was a bad solder somewhere so I've tried to resolder the step button but nothing has changed. Could it be the IC?
