Cit Costco Card is showing each credit card as a separate account. Consequently, there are duplicate entries for the same account.
I recently added my new Citi Costco Visa Card to Mint. Instead of showing all the transactions under one account, it lists the Citi Visa under two separate accounts, displaying the last four digits of each credit card. Each account shows the same transaction though, not just the transactions made by that respective card. Both credit card show just be listed under one account, not two. None of my other accounts do this, and I do not know how to consolidate the accounts into one.
