I complete all “halo 3” and “halo 4” missions at Leggendary.
But thh game doesn’t unlock me 2 objectivies “Complete all missions in Halo 3 at Leggendary” -> The % stay at 88% but i complete ALL missions at leggendary
In halo 4 “Complete alla missions in Halo 4 at leggendary alone” -> same thing, the % atay at 87% but i complete ALL missions at leggendary alone!
View which games aren’t recorded on Waypoint under your service record; that should tell you which ones you haven’t “beaten” yet.
Also, as a precaution, I hear people have better luck when they enable score or time on (idk just the normal one, not competitive) and stay away from XBL parties.
For Halo 4 you’re missing Midnight. For Halo 3 you’re missing Flood.

Also :
This could be 343’s fault as there is currently a bug where if you Save and Quit during the Halo 4 campaign, resuming will mark it as a Co-op campaign. You would need to do Midnight again, solo.
