Negative Credit Card Accoutants

Negative Credit Card Accoutants

Hi

When ever I make a payment to my credit card, it increases the debt, rather then decreases it. so at the moment Zoho is showing that I have - 17,000 on a credit card, where in reality I have -600 which is reflected in the positive figure of amount in bank which correlates to what I can read off my statement.

When ever I add a payment from my bank account the figure just goes more negative. 

Thanks
