Finished Halo 5 with no Campaign Commendations?

Games Halo 5: Guardians
1

I just finished Halo 5 and was confused about not receiving any Campaign Commendations from the game at all.
So, no Elites, Grunts, Hunters, Jackals, Knights etc…
I understand that i don’t receive any multiplayer spartan kills etc, but these seem to be the basic campaign ones?
Is this a bug?

FYI there are no Campaign Commendation. Those commendation are for Warzone.

Ok, interesting.
I thought Halo 5 was set up similar to all the previous Halo 1-4 ‘acheivements’, and could at least get some.
Thanks.
