RESOLVED: Issue with Apple calendar busy vs free?

EDIT: Apparently the default Apple calendar doesn't include a busy/free option, but the third party app I use with my Apple calendar does.

It appears that when I have Apple calendar connected to Fluent Booking all events are counted as unavailable for double booking, not just the "Busy" events.

I have a family calendar that I set several entries to "Free" as they don't affect my availability. Can this be fixed? Or is there a setting somewhere I don't see?
