I'm experiencing this same thing. This started last Thursday 9/7/2017 and is still happening today 9/11/2017.
This occurs the moment I click on the build to provide compliance.
It looks like a javascript crash triggering an internal server error. here is the logdump:
Failed to load resource: the server responded with a status of 500 (Internal Server Error)

This is the very latest Chrome on MacOSX Yosemite, and also on MacOSX Sierra.
