I have installed kubelet 1.26.0 on my Ubuntu 22.04 machine. Previously I had 1.25.2 version that I removed by apt remove kubelet command and reinstalled it with apt install kubelet command. Wherever I search for kubelet's configuration and look at it, it shows the 1.26.0 version, but when I run journalctl -xu kubelet.service it shows the following result:

It shows that the "Kubelet version" kubeletVersion="v1.25.4" and I am also suspect if the configuration is not as I expected and because of that the kubelet doesn't work properly. But I don't know where does this wrong configuration come from and how can I fix it?
