Unable to change a filter type to Checkbox/Radio filter even when the number of unique values is in a supported range.

The option to change the existing filter to a check-box/radio filter is greyed out. When right clicking on a filter, it cannot be switched from the current filter type to a check-box/radio filter though the values are within the recommended limits. The current limit in Spotfire is 100. Some of the values in the current filter are filtered out by other related filters due to which values listed are shown with in limit but actual total unique values for that filter are more than 100.

Reset all the filters and confirm the actual unique values of the filter. https://docs.tibco.com/pub/sfire-analyst/10.3.0/doc/html/en-US/TIB_sfire-analyst_UsersGuide/filter/filter_check_box_filter.htm
