duplicate calendar entries

Recently upgraded mt ATT MotoX to lollipop. I use google calendar for both my personal calendar, and also to subscribe to a work calendar that gives me my daily schedule. When I view this through the google calendar website on my laptop it works fine. However, all of the entries from my subscribed calendar are showing up between 2-16 times on my phone. I've uninstalled the feed, tried turning sync on and off. Cleared all calendar data. Deleted and readded my google account.

Any thoughts?
