Some options of default config.yml don't work as expectation

Environmental Info:
RKE2 Version:
rke2 version v1.22.5+rke2r1 (ce3e572)
go version go1.16.10b7

Node(s) CPU architecture, OS, and Version:
Linux myhsp7 5.10.74.3-microsoft-standard-WSL2+ #2 SMP Sat Jan 8 01:17:54 CST 2022 x86_64 x86_64 x86_64 GNU/Linux

Cluster Configuration:
1 server

Describe the bug:
Some options, node-ip, node-external-ip, in the default config.yml, /etc/rancher/rke2/config.yml, doesn't work as expectation if start rke2 by sudo systemctl start rke2-server. However, if start rke2 by sudo rke2 server --node-ip www.xxx.yyy.zzz --node-external-ip www.xxx.yyy.zzz, it works correctly. We can check IPs in etcd config, sudo cat /var/lib/rancher/rke2/server/db/etcd/config, to see the difference of two methods to start rke2.

Steps To Reproduce:
I created a vlan with a static IP 172.27.137.122 and followed the rke2 quick start with the default config.yml: https://docs.rke2.io/install/quickstart/

sudo ip link add link eth0 name eth0.1 type vlan id 1
sudo ip addr add 172.27.137.112/20 dev eth0.1
sudo ip link set dev eth0.1 up

curl -sfL https://get.rke2.io | sudo sh -

echo "cni: cilium
node-ip: 172.27.137.112
node-external-ip: 172.27.137.112" > config.yml
sudo mkdir -p /etc/rancher/rke2
sudo cp config.yml /etc/rancher/rke2

sudo systemctl start rke2-server.service

After etcd starts, run sudo cat /var/lib/rancher/rke2/server/db/etcd/config to check IPs and you will find they are not IP 172.27.137.112!

Expected behavior:

IPs in etcd config should be 172.27.137.112 of eth0.1, not the IP (e.g. 172.27.140.163) of eth0.

Actual behavior:

IPs in etcd config is the IP of eth0. node-ip, node-external-ip in the rke2 default config.yml don't work as expected. However, cni: cilium in it works (can be confirmed by kubectl get pod -A).

Additional context / logs:

Instead of using sudo systemctl start rke2-server, if run sudo rke2 server --node-ip 172.27.137.112 --node-external-ip 172.27.137.112 --cni cilium, IPs in etcd config are correctly set to 172.27.137.112 of eth0.1.

The file is /etc/rancher/rke2/config.yaml - note that the extension is .yaml, not .yml. This is documented at https://docs.rke2.io/install/install_options/install_options/#configuration-file

Thank you. It works.
