Unhappy with features on playlist – Mixonset: Music Clip DJ Mixer Review

We got this for our wedding (signed up for the premium) but we are having multiple issues with the playlist features. I’m not sure what the problem is. We ticked the “highlight” feature and it only works occasionally. Mostly the playlist will skip a song, shut off or play the whole song. It is very frustrating and I’ll be frantically trying to troubleshoot before Saturday.
