Duplicate iCloud Tabs

Hello. How do I remove duplicate iCloud tabs in contacts on my MacBook pro? There are no duplicates on my iPhone or in iCloud, but only on my MacBook. On the left side of the attached screenshot, you'll see there are also duplicate iCloud tabs.

I've already gone into card>find duplicates>merge. But that didn't help either. They did not merge. Any advice would be appreciated. This happened after I transferred all my information from my old mac to my new mac I just bought.
