Lone Wolf Achievement

I recently beat the halo campaign on Legendary solo - It shows in my service record that I completed each mission solo legendary but when I check my achievement it states it’s at 93%. I do not know what I should do because I do not want to redo each mission again and see which one didn’t go through because It was already a pain in the -Yoink- going through it the first time lol - Anyone know a solution or anyone having the same problem?

UPDATE:
I looked into my service record through here and it show im missing SWORDS OF SANGHELIOS for solo but on mine it shows I did it so I will redo that mission and i’ll post when I finish that up to see if that resolved the problem which I think it will.

According to your Service Record here on Waypoint, it looks like your “Swords of Sanghelios” mission did not register solo completion (but it did as co-op). Just give that another run through and see if it unlocks.

Edit: Looks like you beat me to it.

[RESOLVED] Yeah I posted the update after looking at that and I just finished it now and it registered and now have the achievement. Thank you for the help though.

I’m having the same problem but I’ve looked and it says I’ve done them all.
