itunes 12.3 new albums not displaying / sorting correctly

Strange issue. When I add new albums to my library, they are not being displayed by the column browser correctly. I add three albums in sequence by adding the folders holding the tracks (File...Add Folder to Library...). The first album (for example, "Fire & Ashes") gets listed at the end of the alphabet in the "Albums" column browser, but before the numeric albums (between "The Zurich Tapes" and "#1 Hits Explosion") instead of where it would be appropriate alphabetically. The next album gets added under the first album (if you click on the first new album in the column browser, you see both new albums). Same thing when the third album is added. So you wind up with one album entry in column browser, in the wrong place in the alphabetic list, which contains three albums. I have tried deleting the albums and adding them again in different order but it doesn't seem to matter what order they are added. If I had more new music I'd try to keep adding albums, but thus far I just have the three.
