Multiple copies of my location listed

Thinking of adding a device so for the first time in ages, I looked at my online account.Under "My Plans", my home is listed 13 times with only one of them showing a plan and device.I've tried "Remove Location" and it seemed that might have an impact but no, the extra locations are still listed and now when I try removing them they say "Not Found". It's great thy're not found in teh system BUT why are they still showing up when I look at my account?
