There are a couple things happening causing this not to work, and here are a couple updates I made:
1) Disabled redundant extensions
2) Re-scoped remaining Extension to DOM-Ready
3) Anytime Tracker Names are used they need to be specified in the ga() call. The code from the website did not have any Tracker Names defined. The "utm" and "gclid" Tracker Names were added to the code.
This appears to be working now for the two tags the extension was previously scoped to.
I may suggest that you remove the direct ga() call and replace it with a utag.link function instead. This will enable you to trigger any other tag with this same code base if needed.
Hope this helps.
