Student Dashboard

Hi there!  I am trying to control what my students see when they first log on to Khan Academy because they are in 3rd grade and it is too confusing for them to find the Mission I want them to be working on. We are using EngageNY 3rd Grade, and I am so glad that all the content is on Khan! I have "recommended" that Mission to all students that I am coaching, but each time they log on it either has them select from the personalize list (so they choose 3rd Grade Math, but Engage is not listed as an option there) or when they click on their Mission it shows it as Early Math. I can go around and help them find EngageNY 3rd Grade MOST of the time (sometimes even I get lost) but I don't understand why it doesn't save as their mission. Am I doing something wrong or is that not possible?
