[Closed] Stumped by some weird problem.
I still have to give the replies a closer look and some additional thoughts (+ taking a look at the SMW user mailing list.)
But on the subject of removing the "Running Rabbit Sausage (backup)" page. That page was removed/deleted. And when it was deleted, it had its original content already cleared/replaced with a local {{delete-tag}}.
I just restored that page today (for history restoration reasons). But before doing so I checked if that unwanted second/double linkup was still there, and it was (in this case a link to the, at that moment deleted and cleared, "Running Rabbit Sausage (backup)" page.
Or: Just deleting that page did not work (yet).
I'm getting some additional ideas here. Time to work them out a bit more. ...
Perhaps, you could try to rebuild SMW data for the page Running Rabbit Sausage (backup) (by id).
Shorty after the recent MediaWiki version update of the RoB-wiki site, both the "Database installation and upgrade" and "Data repair and upgrade" where run. (Its unknown if at that point this problem was already there. Although I think it probably was already there, just not spotted yet.)
Those problem pages where also saved without making any changes. Which generally fixes most problems. But that unfortunate did nothing in this case. (Although I'm planning on doing that on all related pages again. Just in case I mist one, and to see if something changes. ... I might get lucky. ;) )
