new contact always pops up with one email address

Recently, when I put in a new contact, there is always one specific
email address that pops up when I get ready to put in the new email
address in.
I have to delete the "offending" email addresses (there are four places
where it pops up in the contact page, ie, windows live, personal email,
etc.) and put in the new one. Yet if I backtrack, it will always re-pop
up with the bad offending email address again and again and again. How
do I get rid of this offending email address without getting rid of the
offender itself?
