Cube powers inside set dungeons

Has anyone else found that their skills from Kanai’s cube don’t work inside set dungeons?

No.

Which class?
Which set dungeon?
Which powers in the Cube?
What made you think they’re not working?

Apologies for the vagueness:
Witch Doctor
Zunimassa
Thing of the Deep - increases gold/health pickup by 20 yards
The Circle around me remained small

Appreciate any advice
