Number of propeller governors on Pilatus PC-6 / PT6

I have a question, maybe it is funny for you, but I can't find answer on google.

So I received status of one Pilatus PC6 with engine PT6A-27, where there is also "Propeller overspeed governor, PN 8210-002" stated, with overhaul 4.100FH.

And on second, different PC6 with same engine PT6A-27, there are two propeller governors stated on Status List.
One is "Propeller overspeed governor, PN 8210-002", overhaul 4.100FH
and second "Propeller governor, PN 210615", with overhaul 6.500FH.

So is this a mistake in status on second aircraft? Maybe someone forgot to delete one governor after replacement?
Or is it possible to have two governors?
