I have merged accounts before without an issue. This week I've tried endless times to simply merge three accounts. Each time I get to the "Yes, merge accts", click it, and then it only gives me the option to Save. I click "Save" and then it gives me a message "Another acct is already using number 7085. Please use diff number."  It just won't save. See screenshots below. Thank you for any help in solving this problem. Kara
