Wizard doesn't like our Owner Information

We just upgraded to 16.0 from 14.4, and I didn't pick up what is probably going to turn into a major problem for us. Many of our owner lines are of the form:

Owner= [log in to unmask]  (Joe Schlabotnik, 999-999-9999)

Manual edit is quite happy, but the wizard is not. The parser sees the comma, and whatever follows (in this case, 999-999-9999) becomes another owner! That is invalid, and when saving, throws an error. We have hundreds (probably over a thousand) in this format and have been that way "forever." School is about to open and lots of people are going to encounter this error- a problem for them and a public relations disaster for Listserv. Yeah, we should have picked this up earlier, but we were in a bit of a hurry to get upgraded, being so far behind.

Any ideas/suggestions? Thanks in advance for your response.
