Configurator 2 - Editing Blueprints gives a blank page
Went to setup another blueprint for my school (~200 iPads) and the Blueprints screen in Configurator 2 is now blank for all my blueprints.
Here's a screenshot. I can't change any settings in here now!
The rest of the app seems to work okay.
I've tried relaunching the app, rebooting etc, no change.
Running Configurator 2.5 on Sierra 10.12.6
Thoughts?
