During testing we experienced progression blockers, crash events that led to data loss such as saved

Like I said, I think it's default text that's added to the report due to the tester selecting the most appropriate item from a list of failure reasons. The lack of login is a blocker so the report has the text for the 'blocker' failure reason. Your best bet is to provide the login details (no idea how you give them that though) and resubmit.
