2 parents can pay for the same student

i have 2 divorced parents paying for one student. When I go back and look at who paid it all says mom paid when actually dad paid under his own separate sign in. This really needs to be fixed they can’t tell who has paid what and neither can I. Why isn’t it marked as the correct person paying. The parent/contact issue needs to be addressed. There should be two separate parent options and a way for me to tell who ordered and paid for items under the account they are logged in as.
