There were some problems while converting those elements to text and were displayed as ‘empty’.
The problem with the ‘Site Location Identity’ and lat-long units is fixed now.
‘Query Site Locations’ and ‘Query Shared Sites’ are returning all locations and sites in the document, internal ones, related to project coord system, too.
I think we should provide a way to filter out those project related location and site elements.
The current Location and Site are returned from ‘Project Location’ component.
I found this article that may help to explain the confusion here.
