Just curious if this is an intentional difference in the series title, since things like this could mess up library sorting/collection rules.
I'm not seeing this, which probably means it's already been fixed, but your computer hasn't correctly downloaded the updated metadata.
You can force a metadata update by deleting C:\Users\<UserName>\AppData\Local\Logos\Data\<random>\Updates, and then opening Logos. You'll get no indication that metadata updates are occurring, except for the message in the library that the Library Catalog is updating. It takes quite a while (20 mins - 1 hour depending on the speed of your connection at the size of your library).
