B67 ARC (Android) shows underscore instead of hyphen in artist name

On Android phone. The artist is 24-7 Spyz. Remotes show it correctly, e.g. the same phone:

In ARC it’s an underscore:

Edit: Actually that is true for many but not all artists with a hyphen. Artist list from my ARC with a filter for “-” shows:

Getting weirder:

In the Album list, one 24-7 Spyz album uses underscore, one uses hyphen, both from the same Artist name

B-52’s have hyphen but had underscore in artist list:

Ignore the question mark at Alt-J please, I thought there was an issue with capitalization but isn’t (just a difference in album artist)
