My FP5 system storage is going bonkers

The system storage space on Fairphone 5 is 35 GB

I’ve got a new Fairphone 5 today and at the first glance to the occupied storage it reported that the System is taking up 35 GB of storage. This is more than 10 % of the total internal storage! In comparison on my Fairphone 4 the System just takes 1.1 GB, which is less than a half percent of the internal storage. So the System storage between Fairphone 4 and 5 has increased by a factor of 30 or more. Why? Is this supposed to be this way? It seems way too much to me. Can anyone confirm?
