Hi …I’ve completed the Japanese 1 Course and also finished the Japanese 2 course. But the Japanese 2 course indicates that 454/455 words learned. Though I went through it again and again, it doesn’t show me what is it that I have missed. Because of this the course is shown as incomplete.
you might have accidentally ignored something, go through all the learning stages and it will have “1 ignored” at the top right
Yeah…I did this…it appears as if nothing is ignored as I’m shown 0 ignored for the overall course as well as each unit 
ah, must be a bug
@LaTheos76, I just encountered the same issue last night. I have been through everything in the course and it is only showing 454/455.
Hello!
This is now fixed
