This is expected as, prior to the fix, the SimpleGlazingSystem could have negative absorptance at certain angles of incidence. For an Ideal Loads Air System, I would only expect to see heating loads decrease because of the fix (which is consistent with what you are seeing). There is now a check in the source code that ensures the calculated absorptance is never outside of 0.0-1.0, so you couldn't change the parameters to give consistent results even if you wanted to.
