How do I build a producer/consumer VI with multiple consumers?

Question

I’m studying for the CLD using this document as a base:
Certified LabVIEW Developer (CLD) Certification and Exam Overview
One of the requirements in that document has me stumped:
6. Select a producer/consumer (events) design pattern to respond to user interface events in the producer loop and defer the processing of the event to one or more consumer loops
I start with LabVIEW's producer/consumer (events) template and give it two consumer loops. However, each event only gets to one of the two loops, not both, as you can see in my attached example VI 1_producer_2_consumers.vi.
I would try LabVIEW notifiers, but I read that a notifer is not guaranteed to reach the consumer loops because they are not queued. I would try user-defined user events which might work, but they are not part of the CLD.
What’s the way to complete requirement 6 above?

you must have a 'queue' for each consumer and you were not properly stopping the loops with user interface (using error handling inefficiently, you will get dinged for it on the CLD)...
