Yet again about flowd_aggregate

[YujiTFD]

Greetings, fairly new OPNSense user here.

I'm sorry in advance if I did miss an obvious info, but all I found regarding "Cannot 'stop' flowd_aggregate." is the issue after upgrading to/from 19.1, while I started with v20.1. It started when I disabled NetFlow and cleared it's settings. After that I started getting 2 warnings:

Cannot 'stop' flow_aggregate. Set flowd_aggregate_enable to YES in /etc/rc.conf or use 'onestop' instead of the 'stop'.
Cannot 'start' flow_aggregate. Set flowd_aggregate_enable to YES in /etc/rc.conf or use 'onestart' instead of the 'start'.

I checked /etc - there is no 'rc.conf' there, but there is 'flowd_aggregate' in /etc/rc.conf.d with "flowd_aggregate_enable=NO", which I switch to "YES" but it did nothing and after reboot has changed back to "NO".
I have a couple of quesitons:
1. What did I do wrong to make warnings appear?
2. Do I really have to make changes in the system configuration or there is another way to make warnings gone? I'm not afraid to tamper with system files, I had some FreeBSD experience couple of decades ago, I just want to make things right the correct way, not make a workaround.

Thank you in advance.

I also get these errors after turning off Netflow.. I also see that there have been no responses to any of the other users reporting the same error from the Opnsense team... Any ideas?

Anything?
