Hello there, ChelleMtoo.
I'd like to verify further details about the restricted account you are using so I can sort things out with you. If there are changes made to a transaction, it doesn't affect related transactions. You'll need to open each transaction and assign the class from there. Then, you can run and refers to the report to see updates.
Aside from that, the posting account affected on the bill is Accounts Payable and it affects the bank account used once its paid and the Accounts Payable account. I'd suggest reaching out to an accountant to help you identify the accounts to be affected when creating a journal entry just not to mess up your books.
You can look into these articles that will help manage your classes and customize reports:
Any additional information about the accounts you used is much appreciated. I'm just around to help you with it. You take care and have a great day!
