TeamBuilder doesnt recognize my ea id when i search for my schools by my usernme

I am having an issue and its really making me very angry because nobody in customer support is helping. So my issue is when I'm in the download center and do a search by username for my created schools the game keeps telling me no matches found.  However, when I go to the tab for my shared schools it shows every single school i created and my EA ID/username is showing at the bottom of the box where it shows the username of the person who made the school.  Since the download center keeps doing this I cannot share my created schools with people and its frustrating me.  I need some help with why this keeps happening because EA Sports customer support team has been no help. They just pass me off with unhelpful links, and suggested that I post something in the forum discussion groups, and i guess hopefully a supervisor at EA will see my post and have someone look into which makes no sense to me. That's like a hope and a prayer answer from customer support for me to try because they don't know what to do to help me when clearly i need a supervisor from tech support or help from someone who has had the same problem.  I have tried to unlink my account then relink it. I have a disc of the game but, i also had a trial version of he game downloaded on my ps5 so i uninstalled the trial version then the disc basically put the game back on my ps5 and none of that worked.  I don't know what else to do other than changing my username and email address at this point ..somebody please help me....because im beyond frustrated with ea sports and their platform...
