Check your credit report for this. Both cards might be showing balances because the first one has not posted the transfer payment yet but the second card shows a balance. To the FICO score it see this as twice the balance. When the first card reports paid the balance went back to where it was and your score will bounce back. It does not count as a new card when you transfer a balance unless you just applied for it. It looks like you doubled your balance on your credit report one month. No harm done. I do it all the time. It only messes with your score for up to 30 days. It can also have the opposite effect too. Credit score can jump and then come back down if the first card reports paid before the second card reports new balance on it.
