Yep, I was having same problems. Apparently it's an Avios issue (as it's their platform AerClub is running on and BAEC also moving there).
Took creating 2 new accounts and some backend wizardry with Avios to resolve.
Problem is that all my flights are registered under old email and account is new email, so two not matching up.
Shockingly bad implementation, apparently 17,000 accounts having issues!
