Battlefield Hardline Achievements

There are 2 bugged achievements and one that I'm not sure if is possible to obtain.

Locked & Loaded, Good to Go (Enter a match after crafting weapons in all five Gun Bench slots) - In this case, it's not even possible to check if achievement triggers since to unlock 4th slot you need to:
- Enter a match after crafting a Weapon in the Gun Bench (in my case 0/1)
- Get 100 kills with weapons crafted in the Gun Bench (in my case 25/100)
The first requirement is glitched, as I shouldn't be able to get any kills with custom weapons without joining to the game with one

Dressed to the Sixteens (Enter a match after customizing all 16 Class and Faction outfits) - I changed all 16 outfits multiple times to different colors, all my characters cops and criminals, have custom outfits enabled in settings.

Test Your Mettle (Complete 25 Competitive Matches) - obviously nobody is queuing in competitive, so you need at least 10 people, but even then I heard it's not possible to obtain

Is there any workaround for these achievements or some tip on how to trigger them?
ea support said in live chat they're going to look at this issue, but that's obviously a hilarious joke for a 10 years old game.
