Payment Arrangement wizard; won't allow final payment date to extend past Maturity date

The Payment Arrangement wizard may not allow the final payment date to extend past the Maturity date. The Account Type shows the option "Allow Payment Arrangement to extend Term?", under Term page, as checked.

This occurs after 1.6.0 or later has been installed and the User is not an Administrator and the Account Type has not been edited and saved. In this case the option is actually undefined and incorrectly treated as unchecked.

To correct, either install the version 1.6.5 of finPOWER Connect, or edit the Account Type, change something and save.
