Expense partly paid with Paypal balance, partly with credit card

Expense partly paid with Paypal balance, partly with credit card

Hi, Ii paid an expense through Paypal but there wasn't sufficient balance to pay the full amount so the remainder was charged to thcredikt card against the Paypal account. When I put the expense through Zoho, Ii could only choose one payment type, so I chose the Paypal balance, however now there is an imbalance as my Payapl actual balance is zero, but he Zoho Paypal balance is showing as a negative. How can I offset this? Many thanks
