US Survey Feet issue / 3-4 ft offset in EGStar 5.0

Hi everyone,
​Following up on my project setup issues: I’ve run into a significant unit mismatch in EGStar 5.0.

​When setting up a project, under the unit settings, the only distance options available are Meters, Centimeters, Milimeters, and Foot. However, selecting Foot appears to default to International Feet rather than US Survey Feet.
​This difference creates a 3 to 4-foot shift in my Northings/Eastings when checking against local benchmark control points.

​Is there a workaround or a specific sequence in EGStar to force US Survey Feet?

​Is US Survey Foot tied directly to selecting a specific Projection / Coordinate System predefined file (.crt or custom parameters)?

​Or is there a configuration file/setting where custom linear units can be defined?

​If anyone working with US State Plane coordinates in EGStar 5.0 has resolved this shift, I’d really appreciate your guidance!
