Can't see full library holdings in Overdrive on KLC

Hi, Everyone.

I can go on my computer or phone and go into Libby and see National Geographic as something I can borrow. But when I go into Ovedrive on my KLC, It's not coming up, and it's not showing up in My Books after i sync. Has anyone else had this problem?

I can go into Calibre and get National Geographic that way, but this would be easier if it worked.
