Recruiting - Define external career site search filters

Summary:

We have a number of segments configured in the Job Requisition Descriptive Flexfield which are used for reporting on requisition data. I have now added another segment which we want to use on the external career site as a searchable flexfield. When setting the Action 'Recruiting - Define external career site search filters' in the HCM Design Studio, we cannot select the one segment to be searchable, it is showing all segments in the Global Data elements. The Global Data elements cannot be made not visible, the field is protected.

I created a separate context of the Job Requisition Descriptive Flexfield, but the Global Data Element segments still cannot be disabled.
