In the main Duplicates screen, click on the View Detail button associated with the guest records. You’ll see the View Detail screen.

In the Guest Records table at the top of the screen, select the record that is not a match to the top record. Click Not a Match to let the system know they aren’t a match. Once Not a Match has been selected, the records will not be suggested as possible matches for each other in the future.

If you merge or dismiss all the records in the Detail View, you will be taken back to the main Duplicates screen. You can also go back there at any point by clicking the arrow at the top left of the window.
