I found an issue about wrong computation of aggregate values.
Here’s a JSFiddle: we have a hierarchy field in the columns, and the second element on the rows is filtered by two elements. Look for example at the Australia/Warehouse value (attached Img1). If you expand the second level then this value is wrong (attached Img2).
The issue seems to be related to hierarchy field. Indeed, if you define the BuinessType and Color as separate simple fields the value is right.
Thank you in advance,
Thank you for reporting this issue.
We will take a look at the described expanding behavior and provide a fix with our minor release with the ETA May 30th.
