MCX8000 sync problems

Hello all of my MCX8000 friends, I am having a problem with my mcx8000 not syncing correctly in standalone mode. I’ve read that it could be the tracks but I tried a couple of others and I’m sure that they are analyzed correctly. I was hoping to get some help or feedback. I’ve tried this with matching the tempo and using sync button but does not work either way. Thank you in advance for your assitance!

Hi. Ive just had a replacement unit delivered today as this was a major problem i has with the first one i had. Does yours sync to a degree, but rarely keeps in sync for the full song?
