This is due to weird track numbering. I'll see if there is a way to fix this issue.

The release has a track 0.

Got it at https://www.discogs.com/Heathen-Apostles-Without-A-Trace/release/5469606
See nothing strange with the numbering.

This also occurs on https://www.discogs.com/release/2408248 which has vinyl numbered from A to Z, some tracks have subtracks with G1.a etc.
