I assume it's
https://getwacup.com/community/index.php?topic=2059.0 that you're referring to as the prior thread which was locked which was done since it was reported as being resolved. I'll have to look into this as I'm not seeing it showing 0:00 but something doesn't look quite right with the time that's being reported in either of the playlist elapsed / remaining modes (the single playlist item seems to be ok). I've also moved this into a more appropriate part of the forum (not sure why visualisation was chosen).
[edit]I see why it's not working though I'm also going to have to do something to try to reduce the time that it takes to calculate things as it's too slow for either of the playlist* display modes & is also potentially behind some of it showing just as the playing position.
