It's not wrongly mapped per se, it just lacks details: this is a building that is on the hospital campus of the Klinikum Darmstadt (so it is definitely not a amenity=hospital itself) that hosts a lot of different doctors offices with different specialities. It sort of serves as an extension of the hospital (e.g. for people that do no longer require permanent treatment at the hospital but still a speciality physician from time to time), see https://klinikum-darmstadt.de/medizin-pflege/medizinisches-versorgungszentrum-am-klinikum-darmstadt

As the building also hosts some other healthcare-related facilities, such as a pharmacy, the current state of the whole building having the "amenity=doctors" tag is not fully accurate but I'd say it's good enough.
At least as long as nobody wants to put in the effort of tagging the different facilities with separate nodes inside the building.
