[solved] 21.7.7 haproxy: "There are pending configuration changes"

[ThuTex]

So, while i had no issues on a 21.7.5 machine, i just setup a new opnsense,
so a completely NEW setup, no tinkering, no importing, no whatever.

while configuring haproxy i keep running into the issue that it says "There are pending configuration changes that must be applied in order for them to take effect. To review them visit the Config Diff page."
and when i hit apply.... it does not apply.
and so, no way to start haproxy.

when i move haproxy.conf.staging to haproxy.conf manually, and start haproxy manually, there is no issue and the gui happily says there are no config changes.
i then change something in the gui again aaaaaand.... broken again.

is this a known issue for 21.7.7 ?
is someone else experiencing this ?

we have opnsense support if needed, so i could always contact their paid support, but before bothering them  like that,
i wanted to verify in the community if anyone else is seeing this.

aaand.... after a decent night sleep and some coffee i went ahead and actually enabled the haproxy service in the config to solve this 

could do with a "make sure the service is enabled" addition to the message...
but then again, could also just notice the fact that the status button is not shown, so... more coffee and sleep.
