Quantized hot cue loop issue/bug/weird

So I was doing some practicing on my XDJ-RX2, had a loop going and noticing how it was getting out of sync. Both songs are grid adjusted, the loop is correctly positioned, the device set to quantize mode.

I'd post this in the RX2 section, but went to my computer to test this out in rekordbox. It didn't slip out of sync, but another issue appeared; the loop wouldn't trigger on the grid. No matter how or where I punched it in, it played off-grid. However, when I punched in a regular hot cue, then went back to the loop cue, it synced to the grid. If I stopped the track and retried the hot cue loop, it was back to off-grid.

Never had this happen before, and this is related to one specific track. Perhaps it's something wrong with it, but since the MP3 is fine, i has to be meta data or something. I tried re-adding the track and re-analyze it. Issue persists.

This is super weird. Not even sure what I'm asking. Possibly something I should share with the Rekordbox team. Anyway, I caught both issues on video:

Note: Both the XDJ and Rekordbox on Mac are updated to the as of today latest versions.
