How to delete a bill when from the Free plan

How to delete a bill when from the Free plan

Hello - 

During my introductory trial period of Zoho Books I explored many options, including creating bills.

Now that the trial has expired and I opted for the Free plan I no longer have an option to view Bills, but (at least) one of the bills I created is clearly still in the system because it is showing as being overdue.  Any time that I try to click on the bill in order to be able to then delete it (for example, from Payable Details report) presents me with a Page Not Found error.

Is there a way to remove bills that were created during the trial period without signing up for the Professional account to re-enable Bills?

Thanks in advance!
