50% bonus Cryo on SNTNL and on ASE Anoints stack?

Anyone confirm if the Anointments for 50% bonus Cryo damage on Action Skill End and the 50% while SNTNL is active stack properly or if the game only registers one? I haven’t gotten the SNTNL Anointment to drop on any guns in my time with Zane yet but already have the 50% Cryo ASE Anointment on a few grenades .
