Qrow only told her about the legends, which is about as informative as the WoR about the Maidens.

Qrow should, at the very least, be expected to have a much better idea of what they are and can do beyond what the mere stories say, since, you know, he trained for years alongside one.

And that's only in regards to Qrow, not Ozpin, who RNJR found out has lived for multiple ages, and thus should be expected to know quite a lot, including about the Silver Eyes.
