Update 2: For example, https://www.wikidata.org/wiki/Q17847522 and https://www.wikidata.org/wiki/Q17847537 have the same Scotland ID, but refer to different entities (church and churchyard, respectively). They were as two entities in the original dataset, sharing the same ID.

Update: There appear to be quite a few items with duplicate Scotland IDs (not all of them may be erroneous!): http://wdq.wmflabs.org/stats?action=doublestring&prop=709

I created (some/most of) these items as part of the Wiki Loves Monuments UK 2014 drive, to run the campaign from Wikidata rather than from a bespoke database. This allows the community (TM) to maintain the data, rather than one poor sod (e.g., myself) having to frantically update all of it every year ;-)
"Consumer" tool is here: https://tools.wmflabs.org/wlmuk/index_wd.html
These are based on "official" data from National Heritage, provided to me via Wikimedia UK. Grade A (or Grade I/II* in England) structures should be noteworthy by default.
It appears (as per your examples) that some of these were created as duplicates/with wrong IDs. As I said, this is based on "official" data, so it's the best I could do at the time. With mass creation, there are bound to be a few strays. If you can find some large-scale, systemic issue I'll try to fix it, but the one-offs will always fall back to manual fixing. At least, with Wikidata, we can fix them together.

Or is the

key?
The uniqueness constraint does indeed not apply if there is no description.
