Hello!
I was using Calibre on a previous computer and had a bunch of custom columns - one for wordcount (using a wordcount extension), one for fandom (I download fanfics to my Kobo using the FanFicFare extension), another for Kobo collections.

When I changed computers, I downloaded Calibre again. All of my documents, including my Calibre library, are in the cloud (mega.nz - kind of like dropbox I guess) so my books all automatically appeared in my new Calibre, but without the columns. When I went to export data from my old Calibre, the columns and extra info was all gone from the old Calibre.

Is there any hope of getting that info back?

I did backup my entire Calibre library prior to changing computers. So I've tried copying the backup on to my old computer and putting all the books back into my old Calibre that way, but the columns are still missing. I'm not sure if the info is gone, or if it's still there but the program doesn't know how to get to it anymore.

Any advice? Thank you!
