Problem with User ID#'s

I have done some cleaning up of my phpmyadmin tables. Specifically I have matched _users ID numbers with swpm_members_tbl ID numbers. There are a total of 139 users/members so I set the auto-increment for both to 140.

Now, unfortunately when I register a new member, it is showing the wrong person. Example, I registered "test1" but the login box shows "garry", who is my brother and a fake user that I use for testing. His profile has been deleted.

I'm assuming that I've missed a table somewhere that is holding on to "garry". Support access is granted. Would appreciate any help. Thank you!
