Sharedfolders problem with docker

I am having problems creating new sharedfolders. OMV always throws an error concerning docker. When looking at outputs, it seems like the OMV process is trying to unmount and remount my docker-sharedfolder, which of course doesn't work when docker is running. Has anyone come across this problem? Does anyone have an idea how to solve this?

Error #0:
OMV\ExecException: Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; systemctl restart 'sharedfolders-dockerfiles.mount' 2>&1' with exit code '1': Job for sharedfolders-dockerfiles.mount failed.
See "systemctl status sharedfolders-dockerfiles.mount" and "journalctl -xe" for details. in /usr/share/php/openmediavault/system/process.inc:182

When I then run

systemctl status sharedfolders-dockerfiles.mount

I get the following output:

● sharedfolders-dockerfiles.mount - Mount shared folder dockerfiles to /sharedfolders/dockerfiles

thanks. I understand.

Unfortunately its impossible to use absolute paths because the OMV drop down for docker files only presents a list of sharedfolders.

any tips on how to get around this?
