I have tried to use the file load workflow as well.
Capture shows the field book is populated with data.
This capture shows the results of the Least squares analysis vertical report. No adjusted elevations seem to be computed. Our firm has 3 first order Leica levels that are out of commission due to lack of software to reduce and adjust the .GSI file format.
Hate to see good equipment gather dust. Thought this might bring these levels back into service.
Fingers crossed.
