The Wikipedia article about Wangerooge describes an island and municipality.
https://en.wikipedia.org/wiki/Wangerooge
These two concepts, island and municipality, have discrete items.
Municipality: https://www.wikidata.org/wiki/Q25135 Island: https://www.wikidata.org/wiki/Q17081143
I would like Q17081143 to point to the Wangerooge Wikipedia article, but adding the link gives this error:
The link enwiki:Wangerooge is already used by item Q25135. You may remove it from Q25135 if it does not belong there or merge the items if they are about the exact same topic.
How can we fix this?
