New balance transfer balance divided up into previous balance transfer balances

I recently paid off a credit card that had a standard purchase and two balance transfer balances. I then did a new balance transfer offer. However, part of it went into the standard purchase balance and the two previous balance transfer balances. Looking at my bill, I noticed that the 3 balance are about 90% of their original balance (ex. SPB was $455 now it is $45). Has anyone experienced this before. I sent a message to my credit card company Citi and I'm waiting to hear back.
