iOS 13 Mail filing has been forgotten

Since I have updated to iOS 13 on my iPad and iPhone it appears that when I go to file emails it seems to of forgotten where to move the emails to.

This used to be really useful for me, I could easily read the mails, etc then click edit, then move and the emails would prompt “Move to X”.

Since the upgrade this has stopped, I was hoping it would learn it again, but it’s been a couple of weeks now and still I am having to manually find and file the mails.

Has anyone else had this issue, any ideas if this will start to work again?
