When you copy from CDs into iTunes, iTunes uses a database named Gracenote to provide the information about the album. So possibly the issue lies with the entries on Gracenote*, rather than with iTunes.
If I'm not mistaken, the screenshot you've posted shows the Windows 10 File Manager. What we see is two separate folders for the artist Soen (I've never heard of them).
For now, I have two questions which should help in working out where the problem lies and what to do about it:
- do each of those two folders have songs from the same album, or do they have different albums? This is a cruicial question. Does each folder (Soen and Soen_) each have at least one song from the same album? The albums Lykaia and Lykaia Revisted are two separate albums (still never heard of them!)
- are the copies of your Soen albums actually from physical CDs, or from digital downloads, or a mixture?
The album Lykaia Revisted has additional songs compared to Lykaia, and the digital version appears to have yet another song. So I can see what may have happened. (I'll explain later, if I'm correct.) I don't know how I know all this about Soen, since I've never heard of them.
If you look in your iTunes Library, do you have the same problem? (It's preferable to look in the iTunes Library, rather than File Manager. The iTunes interface is designed by Apple to be used by you; the File Manager is used by iTunes to manage what you see. If you try to chnage anything about your music in File Manager, iTunes may become unable to find, or play, the music.
* Gracenote's information about an album may be compiled by a bored record company employee, the artist or even by a fan. It's not always correct.
