Without spending too much time on this I see this is related to data densification regarding the State (filter - parameter driven). You have true and null which equates to CA and Null states. Both of those values for state only have Dec 2015 days from Dec 1-11 (Null state) and Dec 18-31 (CA state).
Thanks for the reply John.
You are correct there, but if I remove the state filter, I'll lose my heat map. Is there a way to still apply the heat map, still have my state filter, and have the numbered dates even when null?
