I fixed it!
Although I don't know why what I did worked.

Turns out it was something with my English template. I made a new template and literally copied and pasted all the info from my original EN template to the my new one and changed the template ID in my app and it started working. If I change the ID back the old EN template I get those errors. So somewhere along the way something happened to that template, but it's not in the markup since I copied all that into the new template and that works fine. It must be something else somewhere in files that we don't touch.
Weird.
