“Posts Per Page” Disappears when selecting custom skin in Posts Element.

I have a made a custom skin and when I load it into a post element in Elementor it gets rid of the ability to select posts per page and only shows 3 posts per page. If I select “Card” or “Classic” for the skin I am able to show as many posts per page as I’d like and it works fine. The website is a development website but I can share login information to view if needed. Thanks!
