Icon missing after container move

Hey com…
I want to use different drives for containers and I tested it with ‘syncthing’ on that way:

sudo docker container stop syncthing_server_1
cd /media/ti/Node/umbrel/app-data/
cp syncthing/ /home/ti/containers/ -r
rm syncthing/ -r
sudo ln -s /home/ti/containers/syncthing/ /media/ti/Node/umbrel/app-data/syncthing
sudo docker container start syncthing_server_1

Syncthing is still working after starting the container, but, the Icon is missing at Umbrels Dashboard?

May someone know what to do to get the icon back?
