I had a similar issue when I ripped two CD's by the same artist and the album names were almost identical.
I ended up with one album with two track 1's; two track 2's .... etc.
I ripped my CDs to my laptop and from what I recall, simply right clicking on the album itself and renaming the album didn't work.
I had to open an album and right click on each individual track and select "properties". Then select "details" from the tab along the top and this will display all the details for that track. Click on "album" and rename it accordingly. You'll have to do this for all of the tracks within one of the albums, making sure that you give them all the same album name, but obviously different to the other album.
I think this should work :)
