Let me explain how it works, justineks.

Everything is correct. There are two different amounts because when we record the refund, which is the bank deposit, we've linked it to the vendor credit. 

I suggest not to check it through the vendor's profile. The total that you can see from there is based on the amount per line. You can use the Transaction List by Vendor report. Go to the Reports menu, then search and select the said report. From there, you'll see that the deposit offsets the vendor credit. 

Reply again if you have more clarifications. I'm always here to help.
