hi i setup site strike thing then went to bed slept about 6 hours come back and the targets are still here while im pushing another wall https://imgur.com/a/JcbzBsj is there a way to remove these targets

Targets have a lifetime of 5 minutes, after that they should be removed automatically. I don't know what happened here - first time I hear of this issue.

You can use the console command "AircraftDronesLockdown" to solve this. This command removes all targets and all flares from the map, after that you can start placing them again.
