I was able to confirm this issue and fix it. The sub-heading (Area) was not being printed when using the weekday + area sort. During a previous update, I modified the scope of a variable that controls printing the sub-heading.
This only affected the San Diego Imperial Region as they are the only service body using the weekday + area sort method.
The update (v1.0.9) has been submitted to WordPress.
Thanks for reporting this John!
