The following was a post made 11 months ago.  It seems the problem is not completely fixed Inma as the same thing has just happened to me.

Uh no. So in one lesson you guys said calor was feminine. Even though in three years of Spanish I've always only seen it as masculine. But in fact it can be either according to the RAE. Now in this lesson I marked it as feminine and you guys say I'm wrong. So you guys need to fix this answer or at least be consistent.
