Same address twice in User Accounts

Using Netplwiz, I notice in my User Accounts I have the same User Name twice. Actually it is the same email address twice. Both are administrators under Group. My question is, can I remove one of those without having my computer going into meltdown. Please advise.

Maybe I can get an answer here. In User Control, I have two exact email addresses under User Names. Under Groups, both are said to be Administrators. In the far left of the email addresses, there are two distinct little pictures. The first appears to be some sort of tv screen behind a little mans head and the second one has a little globe behind a mans head.
My questions is, can I delete one of these email addresses or user names?

Taking a screenshot and getting rid of the email addresses seems to prove more difficult than the original question. The best way to explain this from my perspective, it only to say again, that under the User Name there are two exact same email addresses. I suppose I could delete one or the other and hopefully my computer will not explode.
If this is unsolvable apart from the screenshot, we'll just let it roll Brink. It's not hurting anything to my knowledge. Thanks for your reply!

Brink, I can black out the email addresses. It's time to roll over into bed here but I'll upload a picture of that for you tomorrow night if that's ok with yourself.

Here we go Brink. See if this is any help in order to understand what I'm saying.

Good! What would you do if you had this on your system, leave it or delete one of the two and if so, which one?
