Reportable field option not available when editing a field within studio

I cannot find any fields that have the “reportable” option when editing those fields in studio. Specifically I am trying to create an opportunity pipeline report but cannot select any of the fields from the opportunity module. I have already read and re-read the following article:

Current version of CRM
Version 7.2.2
Sugar Version 6.5.20 (Build 1001)

Please don’t write “current version of SuiteCRM”, there are 3 current versions, for the 3 current branches, 7.8, 7.9, 7.10… and 7.2.2 is your PHP version, I assume?

Instead of thinking in terms of setting fields as “reportable”, I would simply focus on why you’re not seeing the fields in Reports. They should be there without any further action.

Maybe compare with the online demo to see if it’s different there?
