Thank you Panther! There is no mention of deaths so what I did instead was fix the second mission and add a new string for Mission 3 to it could go to the next mission.
[2] =
{
["datetime"] = "Sat Sep 5 19:48:38 2020",
["agKills"] = 1,
["aaKills"] = 1,
["stage"] = 2,
["deathsCount"] = 0,
["result"] = 100,
["mission"] = "BNBOB - 02.miz",
}, -- end of [2]
[3] =
{
["datetime"] = "Mon Sep 7 17:03:38 2020",
["agKills"] = 0,
["aaKills"] = 0,
["stage"] = 3,
["deathsCount"] = 0,
["result"] = 0,
["mission"] = "BNBOB - 03.miz",
}, -- end of [3]
