First, the list of every Jacked mode achievements:
The All For One! achievement in Gears Tactics worth 22 pointsApply three or more stacks of Wingman on a single ally (Jacked game mode only).
The You can't see me! achievement in Gears Tactics worth 61 pointsGain a Supply with a Hidden Jack and no other allies in the Supply Point (Jacked game mode only).
The One For All! achievement in Gears Tactics worth 52 pointsHave four squad members with the Jacked status effect at the same time (Jacked game mode only).
The Untouchable achievement in Gears Tactics worth 311 pointsWin a Veteran Mission without taking a point of damage (Jacked game mode only).
The Suit Up! achievement in Gears Tactics worth 372 pointsEquip at least one weapon with all Supreme Weapon Mods (Jacked game mode only).Remember that you CAN'T go back for a specific mission, so if you didn't unlock, let's say "Jack and the Beanstalk", you need to start a new game.
If you pre-ordered the game, and didn't get Cole at Act 1 Chapter 4 (if I'm not mistaken), treat this problem the same way that tracking issues. You get Cole when the problem is gone, at the end of whatever mission you are playing
I'm writting this solution on September, 2022. There are some tracking issues and I doubt that The Coalition will fix them, so I'll write what you can do to avoid this problem. If for some reason TC fix this problem, just ignore the following:

Tracking issues:
I didn't play this game since day 1, so I don't know when was the first time that the game had problems tracking achievements, but it's pretty "common".
The problem is very simple to understand: There are times (maybe a complete week) that the game just "forget" to increase % for the achievements that have a counter for unlock them (like this achievement, Seriously Jacked, or Zed's dead, baby).
Achievements that have 0 increase (Jack and the Beanstalk, or Number 5 is alive) don't have this problem, but if you unlock one of them while the tracking issue problem is live, these achievements WILL NOT COUNT for Seriously Jacked.
For achievements that have % increase, if you fulfill a requierement while the problem is live, that requierement DOESN'T COUNT (For example: Zed's dead, baby - Kill every Deviant enemy, and for this example you killed a Deviant Kantus) while the problem is live, the game never saves that you killed that Kantus.
Because you need 10 achievements for unlock this achievement, that means that every achievement gives you 10%.
If you don't know if the tracking issue is live or not, and you are close to unlock an achievement, you can do the following:
With a 2nd account, play Gears Tactics. Skip the tutorial and start the 1st mission.
Kill 1 enemy, then pause and choose Abort Mission (% progress doesn't show while you are playing the mission)
If the counter for Grubslayer (kill 10 enemies) goes up 10%, the game is running as normal, so you can unlock achievements without problems.
If the counter DOESN'T go up, stop playing and try this method the next day. Rinse and repeat until the game shows 10%
I had this problem with 2 achievements (Jack and the Beanstalk and One for All!). The tracking issue problem is global, so I have 2 dates when the game stopped tracking, and maybe this can helps other players with this problem:
The first time that I found this problem was on June, the 13th 2022 (One for All!)
The second time was on August, the 12th 2022 (Jack and the Beanstalk)
