Removing Stack in Portainer/Docker

Hi,

Im trying to remove a docker/Portainer stack but when i click the check box and remove i get this

Line 20 is this "- /srv/dev-disk-by-label-Nextcloud/Doc/AdGuard1/workdir:/opt/adguardhome/work"

so i SSH'd into the folder and removed both folders and then came back but still the same error.
