Hi @afrikane
Thank you for reaching out about this. We’ve just discovered this issue in the plugin and are working on getting out a fix for the issue.
One workaround I would suggest is removing the Browse Ads button and creating a new button with a link to the following example URL: https://examplesite.com/classifieds/browse-ads/?results=30
Replace examplesite.com/classifieds with the name of your site and classifieds page and that should work. You can find the correct URL by going to your listings page and at the bottom of the page using the filter for 30 listings. The page it takes you to will have the correct URL to use.
Thank you for reaching out about this and for your patience while we get this addressed!
