WP ERP PHP Fatal Error when syncing with woocommere

Hi,
I purchased the ERP and Modules however, I am having issues after importing from Woocommerce. The sync process goes fine and all of the records get imported. We can view most of the users, however, some of them just load a blank page. The PHP error is:

[20-Oct-2019 03:35:56 UTC] PHP Fatal error: Uncaught Error: Call to a member function get_title() on bool in /home/leafittous/public_html/wp-content/plugins/erp-woocommerce/includes/views/purchased-products.php:39

I did a quick search and believe that it may be the same issue as this: https://wordpress.org/support/topic/fatal-error-call-to-a-member-function-get_title-on-boolean/

The site is quite old and there are products that have been deleted throughout the time and this seems the same issue.

Can you please let me know ASAP? I am in a limbo right now unfortunately.
