Hi Pupinko,
I’m not really sure if my answer will solve your problem, but the first thing that comes to my mind, is that the collection Individualprogamme’ don’t have any individualprogrammes in that collection… so maybe it would help if you add at least one, and maybe use Multi-Reference to be able to filter it?
I’m not an expert on this, but I’ve never run into a limit of 5 collections before, even when using the free plan. So maybe this is worth a shot?
Hope it works out for you, and wish you the best of luck @pupinko
Best,
sven
