Capitals in email address causing trouble (BB-6064)

tl;dr the attachment says it all.
I think the following happened. I entered my email address in capitals, somehow bitbucket changed it to lower case as it knew capitals don't matter, but also kept the capitalized one. Now I have both alex.tesfamichael@gmail.com and Alex.Tesfamichael@gmail.com listed as mail addresses linked to my account. Resending verification doesn't help. Removing is impossible due to both being my primary email according to bitbucket(and this is technically right).
