Sync Problem with Nextcloud App

So, I’ve run into the issue on my iPad Pro (2021, M1) that while I can navigate to my desired folder on my Nextcloud via the native IOS file manager, it doesn’t recognize the folder as being available. When I try to open it, the error message says that the “bookmark failed” and that the file supposedly doesn’t exist. Obviously I told my Nextcloud to keep the folder available offline. Doing the same thing via iCloud works like a charm. Is there any way to mitigate this?
