List View Format Stopping at 10 items

I am trying to implement the Profile Card view (https://github.com/SharePoint/sp-dev-list-formatting/tree/master/view-samples/profile-card) onto a list of people with about 100 items.  However, when I apply it it only loads the first 10 items. It works okay if I remove the float:left but then I just have one long column, which is not what I'm going for.  Has anyone else experienced this? I'm not a CSS master unfortunately.

Here is a shortened version:
