Progress bar confusion

Hello! I’m currently preparing for JLPT N4. I’ve been learning grammar points for that level everyday. Recently, my progress bar for N4 has been showing 148/176 but when I learn a new grammar point, it comes from the N3 grammar! I checked the grammar points for N4 and they all have that stamp on them. Am I missing the remaining N4 grammar points somewhere as the progress bar suggests, or is it another case of something?

Are you using a textbook path?
