Creating Groups Hangs

All,

I think I have figured it out.  I was adding single data points so that I could use the Other Checkbox option and did not want some data points to be automatically placed in "Other", but I did not want to group with other datapoints.  I was also trying to "relabel" some of these data points without changing to backend data, duplicating a column with a different header, etc.  After grouped all the items I wanted in Other by my own group name of other, leaving the single items to stay the way they were, it is working without issues.

blindeye and Anonymous, I am note sure if this is why you are also facing this issue, but so far everything is good as long as each group as at least two items.
