Grouping?

Hi! I am trying out your plug-in. The demo shows different galleries and when you click on the first one, a larger window opens to display all the photos inside that gallery.

Mine is doing that, however, on my “Gallery Page” it is displaying all the photos in a gallery instead of just the first one.

My understanding is that just the first photo of the gallery is shown, then once its clicked, a full page appears showing that photo and the ability to swipe through that gallery to see all the photos in that gallery.
Is this functionality only in the pro version?

Thanks!
