i received all triumphs for the completion of the legendary lightfall campaign, now both master mode and the normal difficulty triumph are not obtainable for me, i repeated 3 times the same mission and still have not received the normal mode which gate me away from completion, then i realized just as i was done with the solo calus fight triumph ready to collect the cool ship

Hey there. These triumphs are for playing the campaign missions as part of the weekly playlist of campaign missions, on Advanced, Expert or Master only. Despite the 'any difficulty' wording, playing them on Classic or on Legendary does not count.
