Gmail: My email address is not hidden even though I've chosen "Hide Email address"

[BellyTickler]

Dear Minimalist community,

I've just installed Minimalist on my Google Chrome. I use Gmail for my email. I do not use Google+ with my Google Account. Thus, in gmail, what's seen is just my email address (emaila...@gmail.com). In minimalist settings, I went to Header / Google User, and put a check mark beside "Hide Email", but Gmail still shows my email address. I did click "Save Changes" and Gmail did reload.

Please help.
