Can anyone give me some Insite into what may be causing this issue?
I had three different events similar to this one and they all involve when someone was checking out with PayPal.
From what I can tell 'billto' is created in 'WhosOnline.php':

Code:

/home2/wildstee/public_html/Zcf294AkrVd6csa550FeF/includes/classes/WhosOnline.php

Line #341 :             'billto' => 'address_billing_id',

Code:

Yep, that issue is coming from the paypalwpp.php module; see this (https://github.com/zencart/zencart/pull/7064) GitHub pull request (PR) which is related.
