Prompt Fix is an option available to show comments selectively, specifically on a single POV prompt column regardless of what the values of the other prompt column values may be selected as by an on looking viewer after the comment is posted.
By using prompt fix one has selectively discriminated purposefully against all but one of the prompt columns for context sensitivity.
In the the case of the Checkbox prompt column or any other prompt column that allows the "All Column Values" option to be a selectable option, the Prompt Fix option for that column will not be available.
Notice in the attached screenshots that the prompt object column has the "All Column Values" selected.
Then the resulting cell comment attempt shows the prompt fix option with only three of the prompt columns at run time available for selection but not the C9 Gender column because the "All Column Values" option of the prompt is selected. If one were to deselect the "All Column Values" option and specify one or more checkbox values then the prompt fix option for C9 Gender would be available.
