Forceful Expression and Infusion is not triggered or not visible with cold


I am playing Amara on the Steam version and bought the Designer’s Cut. I’ve respecced Amara to include the Cold Hearted Action Skill Element, that changes the AS Element to cold. However during the gameplay (I was using Face-puncher) it seemed that neither Infusion, nor Forceful Expression is activated as I could only see white numbers. Now I know that cold-damage has an almost white blueish color, but the number of popping damage numbers is minimal when comparing to using the same setup with Soulfire (fire element), which is still working correctly. So either the skills are not activated, or the damage is added together and not shown as different numbers. If needed I will make some screenshots next time I play.
