I think there should be a display change for when there are no background checks. Just having description as a header with nothing below I would say is not optimal.

What I am referring to:

[JohnCox2211]

The new interface looks a lot better, good work. There is some repetitive code logic that should be able to be streamlined with some repeating for loops for both {% for bgType in backgroundTypes %} and {% for bgStatus in allBackgroundHistory[bgType.id] %}.

[JohnCox2211]

Good work, my comments have been resolved, the functionality is there, and the user interface looks great.
