Dear Jaroslav,
The development team confirmed the problem:
Results are stored correctly in ResultsBuilder. Unfortunately ArbitralyResults have not been tested enough and it looks like we have some unexpected behaviour in the ResultsExplorer dialog, part of Structural Analysis Revit extension.
Measurement with different units shouldn’t be grouped together but they are. There is no workaround for this, some development in ResultsExplorer will be needed to fix this.
Thank you for pointing it out!
Cheers,
Jeremy
