Here is one scenario that causes a duplicate amount to show up in my Balance Sheet.

* I receive a mailed check for $4,000

* The check covers 2 invoices, one for $1,000 and one for $3,000

* I go into Receive Payments and record the payments

* Later in the month I download my Bank Transactions and up pops a $4,000 deposit that I am asked to Confirm

* There is no match (probably because it is a split payment) and there is no option to find the invoices to match, but I confirm because the deposit happened.

* My Balance Sheet immediately shows a $4,000 excess in assets.

So, how do I avoid this?

And since fixing it after it happens is nightmare, how do I fix it?
