We successfully have been able to update the emails in a list...
However, we have two lists and two databases
When we uploaded the first list, it worked...
When we uploaded the second list, it removed emails from the first list and appeared to add emails to the second list.

Thanks for posting. Could you provide some more information as what api calls you made to upload the lists? Thanks.
