There's no reason either that Ingrid would know Marian was Zelena or that Zelena would know the ice cream was cursed. Having magic doesn't make you infallible, or immune to someone else's magic. What's really a problem is Zelena knowing that Marian was Marian when the latter hadn't told Hook and Emma.
