Hi Tortenguru, why do you add wikipedia + wikidata of not-existing Articles/Entity? This is just a dead link.
wikidata=https://de.wikipedia.org/wiki/Konditorei_Fromme
wikipedia=de:Deutschsprachige Wikipedia

Alex

"shop=mall" (shopping centre) ?
or "landuse=commercial"
landuse=commercial
shop=*

Hi farukbrgl, please check the type of your new relation.
Thanks, Alex

check taginfo service:
https://taginfo.openstreetmap.org/reports/key_lengths
https://taginfo.openstreetmap.org/reports/characters_in_keys#problem

can you fix that?

I can ensure it is done by hand (no script on my side), but yes, it it sometimes difficult to decide if the original Author did it in a reasonable way. If it is a List or a Building with wikipedia=en:building, then it is clearly wrong. But sometimes it is hard to say.
Many regards, Alex
