I'm having an issue with my Kobo Libra 2.

Whenever I sideload books via Calibre the default font of Kobo disappeares. Somehow everything switches to some Sans based font and whenever I open an ebook there's a notification that Georgia is added as an extra font for the book in question.

This also happens whenever I use this code from NM to refresh the books:
"menu_item :main :Import Books :nickel_misc :rescan_books_full"

Does anybody what the issue is and how can I fix it?

Edit: Didn't find a fix and had to factory reset
