Sometimes I receive LandFX CAD files from a subcontractor in a zip file.  When I open his files and load the lfx file (FX_PROJECTFILES --> Restore --> Import), and then regenerate the irrigation schedule (Irrigation Schedule --> Regenerate YES --> Select specific schedule for a work area), if there are multiple irrigation schedules for multiple work areas, the legend doesn't appear to connect correctly to the work area and instead reloads the schedule as reflecting the entire project.  If I create a new legend and click on the work area, it functions correctly.

So the work area is recognized as valid if I create a new legend, but the schedule he created from it before it got to me seems to have lost it's association.
