my profile email address has changed. but how?

[bumbacoin]

so my email address is
MyEmail@gmail.com,

but now ,profile now lists it only as
MyEmail

and i cant change it ...

i only noticed because no notification emails ..
anyone shed any light on how this may have happened?

edit, tried to change email and now i'm getting emails again (did miss some notifications though),
but email address is still not listed properly under profile details

edit pt 2.
changed password and email simultaneously and it is now showing all proper.
