Having problem with theme shortcode and membership plugin

Hi, one of my theme's shortcodes ( [portifolio] - Mingle Theme) is not displying correctly when I use the membership plugin.

As membership admin everything is working perfectly and displays correctly, but when I see the page as any of the subscription users, the shortcode behaves very strange.

Still work, but does not show the most recent items as it should and shows only 20. The shortcode also stops getting the items from the correct category.

The page in question is already allowed in the subscriptions, but probably is not getting everything correct as the admin.

Images attached for subscription user and admin view.
