Membership premium - How do I access more than most reccent 25 pages in setting permissions in membe

In Membership Premium, when I edit a membership level under either positive or negative rules, when I drag and drop the pages section I can only see the most recent 25 pages added. How do I select the rest of my pages for the positive/negative rules I'm setting? The plugin tells me it is only displaying the most recent 25 pages - how do I get to the rest of them? THANKS!
