DDJ-SZ PADS TROUBLE WITH PAD

Hello, I would like to ask for help to members with a problem I'm having with my ddj-sz.

I use it with SERATO DJ 1.9 + OS X El Capitan 10:11.

But the deck right side, only one of his pad does not respond. all others do. To scour the forum, I found users with similar problems, also no solution.

Whether you are using the deck 2 or 4. This is just the right side of the controller.

Does anyone know how to solve?

Thank you
