Global Mapper v25.0

Wisconsin County Reference System (Vilas) not interpreted correctly by Global Mapper

Software Version: Global Mapper Pro v24.0


I am building a map catalog of TIF files that use the Wisconsin County Reference System (WISCRS) EPSG code: 7638 (WISCRS Vilas). The raster CRS information appears to be written correctly utilizing the correct EPSG code of 7638 (see below); however, Global Mapper automatically sets the CRS to EPSG 7637 (WISCRS Vernon) when loading the map catalog into the workspace.

This appears to be a bug, but please let me know if I am missing something here.
