Eliminate Duplicate Albums/Tracks

[simoncn]

This an issue with ID2v2.3 tags in MP3 files. The ID3v2.3 specification uses / as a separator between artist names and it is not possible to escape the / character to prevent this.

ID3v2.4 has changed this to use a NUL character (0x00) as the separator. This is a much better approach because NUL cannot be part of a tag value. Converting the tag format from ID3v2.3 to ID3v2.4 for the affected album and doing a rescan should fix the problem.
