Docker container reappears constantly after "rm" or "rm -f"

Hello everyone,

I have containers that I want to get rid of because I can't make them work, but I can't seem to get rid of them. I'm using Portainer usually and the remove command on the container works, but they shortly reappear as newly created containers.

I moved to the terminal to try and sudo it out of existence manually, docker ps, the containers are here. So I sudo docker stop , the terminal confirms. Then sudo rm -f , confirmed again.

Docker ps shows they are gone, but a minute later another docker ps shows they are back up again.

I've looked it up online and people mentioned it might be running as a service. The command "docker service ls" returns an empty list.

How can I nuke those containers?
