Shipment Information not showing in customer order section

I'm having an issue wherein my customers cannot see any shipment information under their order information screen. I tried to act on behalf of one of my customers and sure enough, it isn't showing any of the tracking information. I can see the shipment information on the admin side just fine. Below is a screenshot of what my customer sees on their order info screen.

Anyone have any ideas?
