Where is the "Production Department" in the update page of a title?

Digging into the datasets a little, I see there are 31 credits listed in this mysterious Production Department, and there are also a few other dubious departments that can't usually be seen: Electrical Department (6 credits), Script Department (1 credit), Archive Sound (2 credits) and Archive Footage (1257 credits - this is an archive footage department, not the usual attribute).

Given that the least popular "real" department has nearly half a million credits listed, these all look suspicious. A quick look through the jobs listed for each suggest to me that many of these credits wouldn't belong to these departments even if they did properly exist, so I suspect it's not IMDb testing, but that they've been added in error somehow.

But I can't see any way to get these departments to show up on the update form for adding or editing, even URL manipulation (such as https://contribute.imdb.com/updates?update=tt2238032:production_department.correct) is failing for me, so it'll need staff to fix them (and hopefully also preventing any future additions to these non-departments).
