[2020] Flamethrower is not triggering "+ X Armour and protections while channeling"

Strange. I’ve just tested this, and I can confirm the Magma Shell node isn’t working correctly. However, the “Armor and Protections While Channeling” affix worked perfectly fine for me. Could you post your passives and Idols?

Thanks - Could you screenshot your passive trees as well? (press P). I’m trying to recreate your character as close as possible to determine if there’s an interaction that’s breaking the affix.
