On IPad Mail, Inbox folder not displaying properly

A bit hard to explain without the illustration attached, but on my iPad, using iCloud or Fastmail (so its not provider-related), it doesn’t display the inbox folder alongside my other folders for the account. Somehow it does display in the shortcuts/unified folder above. Even when editing the folder list it doesn’t give me the option to display below. On my iPhone Mail app it works correctly. I’ve tried removing and re-adding the account as well. No idea why. Model: iPad Pro 3rd gen OS: iOS 16.3
