I am not connected with FamilySearch.
My reading of the Catalog details is that FamilySearch actually digitised the records, and did not merely "download" them.
Perhaps when the records were digitised by Family Search in 2008-2013, the above volumes were not available to digitise for some reason. Alternatively, perhaps as the FamilySearch catalog is currently locked for system changes, when the new catalog is released, there may be additional records added.
My understanding, for reading other posts on FS Community, is that everything is on hold until the new Catalog is introduced.
This illustrates the "downside" of being able to edit / delete ones comments after another person has responded. I'm sure Maureen provides a suitable answer, but to what question?!
(Incidentally, on the former, GetSat forum one could not make any changes to comments once another participant had responded.)
