No Pain, No Gain achievement not unlocked by Reach

Games Halo: The Master Chief Collection
1

The cross-game campaign achievement “No Pain, No Gain” (Complete 1 mission with the LASO playlist skulls enabled) is not unlocked by completing a LASO mission in Halo Reach. Specifically, I completed Winter contingency with all 13 skulls active from the mission screen. When viewing the last carnage report, my time says 0:00:00 and score says -868, even though it took me closer to 45 minutes, and I had no deaths, betrayals, or any other reasons to have penalties. I am playing on an original Xbox One.
Is this achievement not designed to be unlocked through Reach, does it need to be done within the LASO playlist itself, or is this a bug?

Hi, I completed Nightfall with all skulls on and didn’t get it either. So I suppose you’re correct, it’s just for the other games. It’s a misleading achievement description. Same with the “Wake up buttercup” achievement, I was completing it on lower difficulties but it didn’t pop until I tried it on Heroic difficulty, but this is not specified in the achievement description either.

Here’s proof for Nightfall: Steam Community :: Screenshot :: but the cheevo didn't pop :(
