Hello Alex,
I have been investigating into the sample project that you have provided, and this issue is known. Unfortunately, there currently exists a bug in the UltraGrid where the summaries of the grid are not working correctly if the grid is grouped by multiple columns, with respect to the internal calculation manager of the grid. I am not aware of a workaround to this issue at the moment.
Our developers are currently working on this issue, and I have created you a private support case that I will link to our internal development issue so that you can be notified when a fix becomes available. The development issue's ID is 246298 and the support case ID is CAS-189524-K1R4Q1 and you can access it here: https://www.infragistics.com/my-account/support-activity.
Please let me know if you have any other questions or concerns on this matter.
Sincerely,AndrewAssociate Developer
