netctl using wrong interface

After a recent Arch Linux update, my ethernet interface somehow got renamed from enp4s0 to enp5s0, as shown by ip link. After correcting this in my profile /etc/netctl/dhcp, and starting sudo netctl dhcp, nothing happens for around 30 seconds and then I get "A dependency job for netctl@dhcp.service failed. See 'journalctl -xe' for details.", which I do and get: [...]systemd: Timed out waiting for device sys-subsystem-net-devices-enp4s0.device. So it seems, netctl ignores my changes to my profile and still tries to use enp4s0. Or maybe the old name is cached somewhere in my system? How can I fix this?
