Wrong AVG calculation in Drill Down with null values

[samuel]

Hi,

I have notice in a list report with AVG calculations, that the drill down result was not the same as the original (previous ) row AVG values.

Please, see pictures attached for clarification!


The problem seems to be a null values from the final rows been converted to zero (0.00) values.
As we know, null values should not be considered for AVG , and Count agregated functions.

Please, let me know if there is a way to avoid this behaviour, or this will need a fix!

Thanks
