Raspberry Pi Model 2B - config changes take no effect?

Hi, maybe it’s a stupid question. But all changes I do to the config folder in “/DietPi/dietpi/conf” do not apply to the installed software.
I have readymedia installed and when I change the directories, it will just scan the old ones.

I have rebooted many times and force a reload on the minidlna software.
Also used the “rm /mnt/dietpi_userdata/.MiniDLNA_Cache/* && systemctl restart minidlna” command,
still it only scans the folders selected during config.

Is there a way to force reload all configs?
Do I work in the wrong folder here?

Any help is appreciated.
