Multiple copies of an album that are the “same”, i.e. number and names of tracks appear as one album. If you look at the album, you will see “versions” down the page. If you click on that, it will show the different versions you have, let you pick a favourite which is the default to play. You can select which version you want to play though if you select from versions.

Cheers, Ian
