Second level not even started but course is shown as completed

I created my own course for specific Japanese Kanji. I added all the Kanji to the database and created two identical levels of those. Only difference is that the first prompts on the meaning and the second one on the reading. Strangely, after completing the first level, Memrise doesn’t offer me a learning button on the dashbord view for the second level. I have to go to course details and select the level “by hand”. The course is even shown as 102/102 elements currently, but there should be 204…
Any advice on this issue?
