I'm new to particles and may have missed something but but i'm sure its some bug: When I switch to particle edit from object mode, the hair particles project towards my screen (pictures below). Also im using vertex groups here but its the same problem if I cover the whole surface
As soon as I click particle edit, this is what I see. Note that the hair now leaves towards the right side of the viewport. Even if I rotate my view, they remain in the same place:
