View more pages in the Membership / Access Levels (positive rules)

We are setting up positive access levels for our site. However, we noticed that it's only letting us specify the most-recent 50 pages.

We saw support pages that tell us where to update the membership-config.php file and completed those tasks. But it still doesn't show us more pages. I have screenshots and the .php to show you if that'll help.
