E.g. on Copenhagen, Rosenborg the link address is:
geo:055.68572,012.57742
On Brampton, Art Gallery of Peel the link address is:

So it seems that the problem is that negative latitudes and longitudes are not handled correct when generating ZIM files.
Thank you very much for this bug report. I can not confirm it, but will check soon and try to fix it in August release.
Fixed, visible in the next (August) version of the ZIM file of wikivoyage. Thx again for this report.
