Dying light bandits glitched out or something?

So im playing dying light for xbox one and I'm doing the side quest goodnight mr. Bahir and I killed 2 of the bandits and now it still says to kill the bandits when they are not there, there is white arrows on my map but no one is their, can someone help?
Sorry if this is confusing but if someone can help that would be much appreciated

Dying Light - Trespassing achievement glitched

Dying Light had the problem since the beginning, My Achievement was glitched for a while until one day it unlocked.

 

Dying Light - Trespassing achievement glitched

Hi, some achievements are bugged in this game. The developers recently released a few patches to fix a few of them.

I would personally post on the developer's forums to see if they have any known workarounds.

I did a quick search and have not seen anyone else have this issue, since this quest is early in game I suggest having a friend who also has the game create a new savegame. Then get up to that stage of the quest and complete it with them, this should also
trigger it in your game again.

You would have to join your friend's game since your mission appears to be glitched.
