Thanks.

When I click on https://docs.google.com/document/d/1G6lmh0LcxFtT3RwiwBenEOqFc2mRE_41XKTr4YkWuS4/, I get a message that authorization is necessary. Please could you copy the document to a place which is public?

I wasn't using HotCat, GeographBot or DPLA bot. I think it happens to me consistently when I use AutoWikiBot.

Hello. This issue is very troublesome for me (at least I think it is the same issue). It happens just about every time I add a "depicts" property to Commons using QuickStatements. I add a caption at the same time - that works fine. The file page history is correct. Then I look interactively at the "Structured data" tab in Commons and there is nothing there under "depicts" or anything (really there are many claims). A current example showing the problem is File:Baltazaria octopodites (10.3897-mycokeys.37.26303) Figure 3.jpg.
I don't know how to make a null edit interactively, but I find that if I next add a "depicts" claim interactively, it suddenly starts working and I can see all the old claims. So I suppose it must be a bug in the "Structured data" display page(?).
