Calculation Statistics: Cells updated says 0 but does not show up in "X Rules produced zero cells"

Hi All,

We have a model that has 117 total rules. When we run the "Calculation Statistics Report" in Calculation Analysis, I can see that 104 rules had 0 for "Cells Updated" statistic. But in the warning of the model run, it says "88 rules produced zero cells".

I then saw that some rules that listed as 0 for "Cells Updated" had calculation results in the system (we cleared calculated results before running). Is there a reason why they are showing as 0 for cells updated? Is there a way to identify the true 88 rules that didnt produce values?
