Draft class import failing 10+ years into save

I have got to my 14th season of a franchise save where I have been importing and using old draft classes and I have had no issue until now. No matter what I try (closing and opening madden, resetting my Xbox, downloading the draft class outside of franchise and making sure I am connected to the servers) it still won’t let me import any more draft classes. I’m not sure if there is a limit to how many times you can import a custom draft class in a save (if there is that is a complete and utter joke) but I’ve tried several different draft classes and it won’t let me import any. Is this a known bug with any fix or is that my save completely ruined now?
