Field not showing up in one environment only

I am having an issue with one of my reports where one of the columns in a grid isn't showing any data. The column is generated by applying a rule to some of the data in a datasubset. It was recently promoted to our production environment after testing in both are Development and Test environments with no problems.

Oddly, when I look at the interface that the report refers to the column displays correctly, so the only place it isn't working is in the report visible in tempo in one environment. Any ideas about what might be causing this?
