U-Mix Control Pro 2 - Intermittent Problem

Hi Mixvibes,
I recently purchased the U-Mix Control Pro 2 - It really is great. So good that I could end up single at this rate!!
I have a problem with deck 2. The play button seems to intermittently act as a cue button. Originally I thought it maybe completing some kind of double click/double action i.e. play/pause in one push, but I have since been compensating for the issue by holding it down for a couple of seconds but then it stops when I release it.
The controller came with Cross 2 and I recently upgraded to 3.3.9 but the problem persists.
Is this a hardware issue or can I fix it?
