Issues with U-Mix Control Pro Audio Output

Hello MixVibes Community!
It's been a while since my last post here...as they say, no news is sometimes good news. There's probably not a lot of people still using the MixVibes controllers, but I'm a creature of habit and convenience and I haven't really had a need to switch to anything else since purchasing mine back in 2011/2012. That being said, my hardware and the CrossDJ software have worked fine up until recently when I started noticing something a bit strange in regards to the audio output. I had two gigs over the last few months where I noticed that the cue track audio was bleeding into the track that was currently playing. At first, I thought this may have been my old issue where I had switched the speaker inputs from 1/2 to 3/4. However, after investigating further, I don't believe that was the issue.
I've checked all of my settings in the Cross software and I can't seem to find anything that will resolve this. As you can imagine, while playing music live, this is a very annoying and potentially disastrous situation, so I'd like to get it resolved quickly. Something I did notice, which leads me to believe that this may be more hardware related than software or PC, is that the issue seems to only occur when the fader switch on the controller is all the way to the left or right. If I move the switch just a little bit inward (the opposite direction of where it's placed), the audio bleed disappears and the fader works as it should when transitioning from one track to another. It's one of those things that I didn't notice right away, especially since I was able to hear the cue track just fine in my headphones until I was ready to start moving into the next song.
So given that all of my cable inputs and settings in the software seem to be correct, has anyone else had this issue or something similar? Any ideas on how to fix it? Could it be a firmware issue or just a hardware issue that comes with wear and tear on the controller? I imagine that MixVibes no longer offers hardware support for their controller unit since they're now focused exclusively on the software and apps, but I'm hoping that some of the experts on here will have a solution or some advice. Thanks in advance!
