Topf Secret: "Antique Restaurant" Leipzig duplicated even though it appears only once in OSM

[rugk]

STR

1. Go to https://fragdenstaat.de/kampagnen/lebensmittelkontrolle/app/
2. Set the place to "Leipzig".
3. Search for "Antique Restaurant"

What happens

It finds two entries:

1. Antique Restaurant Syrian Cuisine
   OpenStreetMap

   Karl-Liebknecht-Straße 106
   04275 Leipzig

2. And: "Antique Restaurant

   Karl-Liebknecht-Straße 106
   04275 Leipzig"

As you can see, the first one is correctly linked to OSM the second one somehow is not and it is duplicated.

At the time I am writing this, none of these does have any FOI requests, so it also should not be a manual addition?

What should happen

These should be merged or so?
