Grammer levels not available for Italian 1 in the app

Hello, I have been doing the Italian 1 course with a Pro subscription. On the web version it says that the grammar lessons are only available on the app. That’s ok for now, but also on the app they don’t show up for me. I’ve attached a screenshot of the app. The grammar lessons should show up as level 2 and 4, as those are the grammar levels on the web version.

Also in the settings on the dashboard of the course, there is now option to select grammar session.

How can I learn the grammar?
