Frost immunity does not remove the encumbrance effects cold blooded units suffer in cold climates. Frost/heat immunity only removes the +2 severe cold/heat encumbrance effect you get from +3 cold/heat scales.

Very easy to test, start as any cold bloded nation, give them +3 cold scales, and put a Ring of Frost on one of the commanders. You will see the +2 encumbrance effects of the severe cold disappear, but the unit will still be suffering from the +10 encumbrance caused by the cold blooded tag.
