Local member deflections are associated with the principal axis. The exception is when the "Laterally Restrained for Torsion" option is checked for use in the section properties. In that case, the local member deflections are associated with the geometric axis.
The design checks should be correct. The program does use a conservative approach when checking lateral-torsional buckling (AISC F4.2). AISC permits equal leg angles to be designed with respect to the principal axis or the geometric axis. RAM Elements checks both. There is a logged enhancement request (Enhancement #277754) to add a user option to select one or the other for design. Some engineers choose to design equal leg angles with respect to the geometric axis only.
