Bad links in Multiple external IDs list

[Former user]

If you go to "Manually sync catalog" there is sometimes a section titled "Multiple external IDs for a single Wikidata item in this catalog". The links under this section seem to all link to non-existent Wikidata items (such as https://www.wikidata.org/wiki/Q115105823).

I noticed this in the following catalogue which has many false positive auto-matches to duplicate location-based items: https://mix-n-match.toolforge.org/#/catalog/4582
