Albums Not Sorting Correctly

[Molf]

I've been using PP for years, but recently I've noticed new albums added to the library are not sorted correctly by Artist. If, for example, I add an album by Abba, it should be first on the Albums library screen, but it comes in at the end of the 'A's, rather than at the beginning.

Same for any artist - any new album added appears as the last of the alphabet letter they come under rather than correctly alphabetically. So, I could add A Kind Of Magic to my Queen albums and it will appear after, say, The Works, rather than before A Night At The Opera, as it should, alphabetically.

Hope that makes sense! I've tried refreshing the library but that has no effect. There doesn't seem to be a way to fully reload the library. Can anyone help?

Thanks.
