Wrong number of active assets

Hi,
we run into a struggle beginning with 16th October, I suppose.
Under the Site-Details, assets, which are active, are missing.
We have 15 on a demo setup, running a scan, scans 15 of them, all is fine, hosts are fine, results are ok.

However, only 8 assets are shown on the assets menu as active, and on the menu of the site the assets belong to, sometimes the hostnames are missing, only 8 of the assets are marked as active and so on.

I am confused. :frowning:
Any ideas?
Best
Ronny
