Matomo showing internal urls in the Acquisition/Websites list

Hey there,
today it came to my eye that matomo is showing internal urls/paths (e.g. in the Acquisition/Websites list which is strange for two reasons:

  1. it’s the own domain (for this idsite)
  2. it’s not just the domain but the whole path in the list

Anyone how ran into that before, too?
Is it a configuration issue?

I can happily provide more details if needed.

Version running: Matomo 3.8.1

Thanks and all the best

The domain of the entry is listed in the site configuration.
