It could very well be because of the dhcpcd.service you're using.

I don't know what it's like on Raspbian, but on Debian this unit appears 
to have no ordering with respect to network.target or network-pre.target 
at all.

On Fedora, this unit is Before=network.target, but it has no ordering with 
respect to network-pre.target. So even there this wouldn't help you.

In my experience a lot of network management software's systemd units 
don't use these target units properly.
