Listing multidisc albums with different composers

[simoncn]

To get the discs merged as you wish, you should not use [disc 01] in ALBUM tags. Did you do a MinimServer rescan after adding these back? Without a rescan, the tag changes you have made will not be seen by MinimServer.

I can't tell from the screenshot you have posted whether these artist entries have been added by your control point or by MinimServer. Which control point are you using?

COMPOSER tags have no effect on album and disc grouping but ARTIST and ALBUMARTIST tags do have an effect. To be sure that the discs are all grouped together into a single album, it is best to set a single consistent ALBUMARTIST for all files on all discs. You can then do anything you want with your ARTIST tags.
