Browse Files not consistent in Web (Chorus) i/face

Hi,
For my multi-channel stuff, they’re all in a single folder in Explorer, & named artist - album (see below):

However, when I view via the Web i/face, in Files, some of them don’t display artist name, only album, however in OSMC or Iphone app, they display correctly, a bit baffled?

Just to update, I found that if I had 2 spaces following the hyphen (between artist & album title), it displays correctly.
