I assume you tried "Show Empty Rows"? It's under analysis, Table Layout.
There's no data for Rating Category 1 or 3 yet. I need to force the table to show data that doesn't exist yet. Even if that option is checked, the report row for Rating Category 1 and 3 will not appear.
Have you tried wrapping the measures in ZN() ?
I encountered a similar problem before, when ZN() didn't work, I tried ZN( countd( [Measure] ) ).
In your case, measure may be [Recommended Comments].
