clearing down payment with account payable

hi all,

I have journal for down payments with tax account.

Down payment vendor 100 USD

Tax 10 USD

BANK (110) USD

account down payment set for net price.

Then journal account payable :

COST 100 USD

AP (100) USD

next step, clearing down payment account with account payable, using F-44 (clearing vendor)

but why when processing open item, amount not zero balance.

account down payment for clearing display amount 110 USD.

and account payable display amount 100 USD.

10 USD, difference amount must be posting to some account for balancing journal. But I think correction posting not correct.

why system not appear down payment amount, only 100 USD ?

can share any link for me, to understand clearing processing ? or different method net and gross down payment process?

Thanks,
