Icici bill payment query (Unipay)

Hello,

I have made 2 icici cc payment of 1000 rs each using debit card via sbiunipay one transaction was successful and credited to bank and other one showing failed in unipay and 1000 rs amount was debited from the bank but here is the real query in icici app 2nd payment was showing credited as my FULL OUTSTANDING amount i.e around 20k rs. So now my cc bill showing as -1000 rs as total outstanding Is that any glitch or what?
