When you're busy managing a business, the last thing you should have to deal with is an inaccurate record of transactions. Allow me to share some information on how to restore your transactions as it was before.
One possible reason you're not seeing some of your paid invoices on the project page is that the transactions were deleted. To check on the changes made into your account, let's pull your audit log.
Go to Gear icon.
Select Audit log under Tools.
From the Filter drop-down, choose the appropriate User, Date and Events filter.
Once completed, if the transaction is deleted, you may create a new set of invoice payments in the system.
