Possible Bug with Exercise Order on App

So far I’ve only noticed this with the Japanese Course but I’m not sure if it is course specific or because I am new to the course.

Some days I try to use the order of exercises that Memrise presents because I imagine there was some testing or science to come up with that order. So when the Japanese 1 course gives me “Meet the Natives” I click on it only to be told I have not been doing the course long enough to use the Meet the Natives exercise.

I’m not sure why the app suggests it if it is not available yet.

I should add that I ignored some of the first words as they are in Romaji which I’m not interested in. I’m not sure if that would affect it,
