Why am I being presented with multiple sources based on the same record?
It is not unusual to find multiple sources relating to the same event in FamilySearch, but these generally represent a different "original" (base) record. However, this year I have been "swamped" with sources for my Yorkshire ancestors / relatives. An example just checked out provides six sources - four dated 11 August 2022 and two dated 17 February 2022. They all contain the same reference of the Archives where the original parish register is held and are part of the same collection - "England, Yorkshire, Parish Registers, 1538-2016". The only difference in the detail shown (apart from the URL, of course) is the place of residence of the bride and groom.
My query concerns how this is happening. I could understand is there were originals and transcripts involved, or if the dates shown were spread over a long periods of time (multiple indexing), but how have up to six records of the exact same material been indexed, apparently on two occasions this year?
Assuming there were two projects that didn't get linked together, is it usual for separate indexers to submit work, which is then processed without any checking that the work has been duplicated?
I would stress this does not apply to just one or two members of a particular branch, who lived at the same or nearby locations. There are multiple families involved from different parts of Yorkshire.
I would be grateful for ideas on how this might have happened in this instance (yes, I'm quite aware of the "usual" reasons for duplication of sources), as it is causing me (and others) considerable effort in adding an unneeded number of sources (usually with identical data) to these Yorkshire families.
