Unable to play entire playlist

I currently have Cue installed on my website, and I’ve added about 25 tracks to the playlist. However, when I go switch to another song, it is stuck on that second song and I am unable to play other tracks.

I can switch to multiple songs on other people’s players, but mine doesn’t do the same for some reason. Any help or insight would be much appreciated.

This is the link to the player: https://www.bccmusic.ca/horizons-prelim/.

Thank you!
