Web Services on cRIO-9068

I am setting up web services on a cRIO-9068 following the guidance here:

https://forums.ni.com/t5/LabVIEW-Web-Development/Getting-Started-Series-Hosting-Web-Service-on-a-Real-Time/ta-p/3512259

However, in Web Service properties, the HTTP Method VI Settings section with the Web Services (URL Mapping / Output Type / Security / Advanced tabs is disabled/greyed out. Does the web service need to be enabled elsewhere for this to appear? My files show up on the site map with each method and URL mapping listed, just not within.

Thanks
