Hello Steve,

Thank you for getting back to me.

I investigated your sample and I was able to reproduce the behavior that you are describing.

I have created a private case for you with an ID of CAS-172145-H4Q8T6 and I will continue assisting you via this support case. You can view your cases in your account on web site under Support Activity.

Please let me know if you have any additional questions.

I added 2 new files to your example, igGridGroupingCustomSummaries.html and igGridGroupingNoSummaries.html.  Couple of notes, upgrading version was not the cause of the issue I just hadn't noticed it before cause all the columns I was doing custom summaries on were a single word key like COST and I was not using any text for custome summary, So the issue comes up only when custom summaries are defined, if you move any column to the group by areas you will see this TOTAL_COST Total Cost: 10 in custom summaries example, my issue is it is including the column key and not using the header text like it does if you do not define a custom summary and drag a column into the group by area when it displays just the count.  Hope this explains the issue a bit better, sorry for my poorly defined original post.
