Do they start when you "systemctl start ..." them when the machine is up?
If not there's a bigger problem.
If yes, the service file(s) need to be modified, I'm using

After=network.target munge.service autofs.service

because my /home directories are automounted and /etc/slurm is pointing to /home/slurm/etc

Quite probably a dependency between services.
