Hi there! The seller pages have a bug we’re currently working on. When we migrated our seller database to the new Publishing Portal, a few sellers didn’t have their correct Epic ID associated with their seller account. I’ve been going through fixing the ones I can find today, and we’re working on a full solution for this. Sorry for the glitch, fixing as fast as we can. 
Have you noticed any more beyond those?
Also, that’s peculiar that the submission guidelines link is broken. The new location for that is here: Epic Games Technical Support & Customer Service | Epic Games But the old one should still work. Will look into. Thanks!
