H4 - Solo completion counting as Co-op!?

Games Halo: The Master Chief Collection

So…

Yesterday I completed the level Infinity on H4 solo, and at the end I got all 3 co-op completion achievements (normal - legendary). I thought it was just a weird achievement glitch at first, but checking my progress on waypoint today, I see that Infinity and Shutdown both show as being completed co-op instead of solo.

This is a rather annoying bug, as it will take me another 2 hours to do these levels again on Legendary to hope they register as solo the second time.

Has anyone else encountered this bug? I thought I had better report it anyway.

Let me guess Forerunner, Infinity since there the ones that for some odd reason counted as co-op instead of single player while Shutdown, Midnight don’t even register at all.

Did it to me on shutdown
