Why can I group but cannot summarize the same field on a report?

I'm not sure what is different about this data sheet. I can 'group' my report by industry vertical; however, when I try to summarize to show a count by Industry Vertical that item will not show in my drop-down in the Summary. I thought perhaps it was because Industry was multi-select, but I changed it, refreshed, and still cannot see it. I summarize by this column all the time on other reports. Any ideas?
