I got by EE.
I opened a GCkey account, created a profile in it. Deleted the GCkey account later and the profile in it still exited but I could not access it because I had revoked the GC key account so I was in the pool.
Went ahead and Created a new GC key account, created another profile and got into the pool.
Received two separate invitations to apply in the two separate accounts.
Since I could only access one GCKey account, I used just that one profile to apply.
And got an approval., I think you may have a problem if you have two invitations in two different accounts and use both accounts to apply without linking them( I don't know how to go about the linking but it is done)
