Duplicate products with wrong Content Id

Hi

In our FB catalogue visible on commerce manager there are few products whose Content Id (Item Group Id)is non numeric in the form of a link. These particular products are displaying wrong prices and are visible in ads too, hence creating a situation for us. There are same products with correct info too. Where should I look further to resolve this. Below is an example-

Item group ID (Correct priced product)
7082_2006

Item group ID (Incorrect priced product)
