I'm using Rancher UI and it is installed in a k3s cluster. Something I didn't realize is, I could actually manage k3s upgrades via Rancher UI itself. Silly I suppose, but I found out Rancher does have this capability and had done a manual upgrade of k3s nodes external to rancher at an earlier point in time. I'm running v1.27.16, but the Rancher UI is showing v1.21.9.
How can I get this version mismatch fixed?
