Payements on term can't be deleted

Hello

I face an issue on payements.
I have a project expense.
I create corresponding order to provider.
I create two termes for order (60% on order and 40% on delivery).
I create first payement for term 1 and it is set to 'paid' as expected.
But if i delete payement then term keep setting to 'paid' and i can't change it. Trying to delete term leads to error 'can't delete paid item'.

Regards
 

Hello,

updating term only leads to check "done" status" but not uncheck "piad" even if no payement are recorded.
