Listed devises

I had several Norton 360 accounts to cover about 8 pc's i use for my small business.

I had a customer service rep cancel all those subscriptions and give me a credit for Norton Security Premium.

When i look at devises under my account there are about 28 or so devises listed with all the same name.

I went through and deleted all the false devises but i am still left with 8 devises with the same name.

I know how to rename the devises, but i have no idea how to properly ID them from the manage support page.

please help
