Thanks for posting and trying to help out Josh. Really appreciate it!
Actually having more than one listing claimed in either the same OR different accounts is a violation, so you need to get rid of one of them. Plus having 2 claimed creates NUMEROUS types of tech problems. (Data changing, can't reply to reviews, images won't upload, all kinds of weird stuff can come up.)
There are not 2 listings live on maps, the 2 have merged together into 1 listing if both links to view on maps go to the same place.
I bet stats are the same too right? That's a definite sign they've merged.
So you need to get rid of one. It's hard to advise which one without seeing everything and doing a bunch of research which I don't really have time to do. But one needs to go.
VERY important, when you decide which one you are getting rid of and hit delete, there are 2 options. If you select delete from maps it will likely delete EVERYTHING because the 2 are merged. So be sure to select, remove from my account.
THEN if the listings are different (mainly if any differences with NAP) there's a chance the one you release will show up live on maps as a separate dupe. So be vigilant and search to see if that happens.
If a live dupe pops up use the Troubleshooter not report a problem as that will get you in touch with a live support rep.
Note Josh: if you ever need to deal with a dupe "report a problem" is no longer the best option. Troubleshooter is best. PLUS you could not report a problem in this case because there is no separate dupe, they are merged and someone in maps could end up deleting everything because they can't see what's in dash to know you have double claimed listings.
Hope this helps and best of luck!
