Help with Duckstation save files and FolderSync

I'm having a problem with Duckstation save files and FolderSync app. I’m setting up the sync to transfer saves between RP3+ and Odin 2 using Google Drive. Everything works except Duckstation save states.

Save states from RP3+ go into the cloud just fine. But when I use the Odin and make new saves, they won’t sync to the cloud. It’s not a permission issue because other apps sync just fine.
