Child Node List LIMIT? (nodes.widget.child-node-list)

We're using the Child Node List component on a group category page, and it seems to max out at 30 items. We have more (in this case) regional groups than that.

Is there a built-in LIMIT to this? If so, how can we increase it? If not, where else can I look to figure this out?

The component itself says it's not configurable. Is this something we'll have to ask support to increase the LIMIT on? 

Thanks
