Start up error - unable to find backends

Hi. I am currently trying to load some backend configurations via an external file, which are passed in on startup. This is HAProxy 1.8 on RHEL
If I run the start up command manually (backends.cfg is the external file to load)

/opt/rh/rh-haproxy18/root/usr/sbin/haproxy -Ws -f /etc/opt/rh/rh-haproxy18/haproxy/haproxy.cfg -p /run/rh-haproxy18-haproxy.pid -f /etc/opt/rh/rh-haproxy18/haproxy/backends/backends.cfg &

it starts up fine.
When I move the option into the startup config in
/etc/sysconfig/rh-haproxy18-haproxy

Add extra options to the haproxy daemon here. This can be useful for

specifying multiple configuration files with multiple -f options.

See haproxy(1) for a complete list of options.

OPTIONS="-d -f /etc/opt/rh/rh-haproxy18/haproxy/backends/backends.cfg"

I get errors of unable to find the backends

systemctl status rh-haproxy18-haproxy.service

WWW & SALES-API are the backend names
These files load and startup correctly on a manual start

Any ideas please ?
