Yellow Flag/caution flag event triggers

Recently I noticed on my last couple broadcasts that my caution events in my theme haven’t been triggering at all.
Today, I looked at the event log during a live race test broadcast, and noticed the yellows/caution aren’t showing up in the event log at all. It’s like iRacing isn’t sending the flag info to ATVO.
Any ideas what might be causing this?
Thanks a bunch!

The Caution event is being triggered just fine in my testing. The FlagYellow is not, I think that is for local yellows which isn't really useful for broadcasting as you only get them for your own car.

Yes, that was the issue, Nick. Changed it to Cautions and works great!
