Hi Toni, I've had a quick look and some of the sources listed have email addresses attached.
As you are the PM (profile manager), it is perfectly acceptable for you to simply delete the email addresses and then save.

"Instead of putting email addresses in sources, options include: removing or redacting them; for an institution, a URL link to a contact web page; and for an individual, a link to their WikiTree profile (perhaps just a dormant guest one) so they can receive private messages as described above"
