I've got something that's just baffling me because I cannot reproduce it on any other album I've tried.
I have 2 versions of David Bowie's 1. Outside album:

As you can see from the image, Version 2 is missing its decimal point after the 1 even though there is one present in the tag:

I've tried clearing the tag and typing it in again. I've tried copying the tag from the correctly displayed album to the incorrectly displayed album, all with no change in behavior. Thinking it might be related to the colon, I tried reproducing this on another album with numbers, added a decimal point, a colon and more but everything still displayed correctly. It's just this one album and it's driving me nuts! If I change the space in the tag to an underscore however, it displays the decimal point correctly, but of course I don't want to do that as it corrupts the tag.
Any ideas what might be happening here or how I might go about fixing it? I've also rescanned the folder with no change.
