One Entry From a Credit Card Statement Upload Appeared in my Current Account

One transaction from my NatWest credit card upload (a .qif file) ended up in my NatWest current account. Other transactions in the same upload ended up in the right place.

Not a huge problem since is the first time it's ever happened (that I've noticed, anyway!) and, since it was only the one transaction, I just deleted it from my current account and entered it manually in the CC account.
