AffiliatesWP's menu tab is not working with Support System's support page

I am using “AffiliatesWP” on my site and I also have the “AffiliateWP – Affiliate Area Tabs” installed to create custom menu tabs in the affiliates area and for some reason the Support page of Support System plugin is not loading any content when I create a custom for that page.

I checked it and the Ticket Submit page is working fine, but the Support page is not loading any content at all, not sure why.
