Chart of Accounts -> Accounts Receivable is listing void receivables and adding them to the accumulated balance. There is also a typo in the “Opening Balance” string. It is displayed as “Opening Balnace”. The “n” and “a” are the wrong way around 😉
Thanks for informing us. We will surely recheck this section before next release.
We also noticed the spelling mistake 😉 and it’s already corrected and will be available in the next release of WP EPR.
