Error in Testing, Lesson 5.2

In the testing for Lesson 5.2 is an error. In Hear it Say it, the speaker says, "Je cherche un toilette," but the revealed sentence is, "Je cherche les toilettes." The same problem is in Rocket Record. Just thought you would like to know.

Either my hearing is poor or the sound quality of my computer is poor, but I'm definetly hearing the word "une" when the text is "les". I did make a mistake in my original comments. The incdences are actually in the testing Hear it Say it, in Write it, and in Know it, as well as in the Lesson 5.2's Extra Vocabulary.
