Nodes stuck in deleting

Bear with me if this has been answered elsewhere. An RTFM response is most welcome if it also includes a link to that FM info.

I deleted two worker nodes from the Rancher UI and from the Cluster Explorer / Nodes view they’re gone. But from Cluster Management they’re still visible (and offline). If I click on the node display name I get a big old Error page. If I click on the UID name, I at least get a page with an ellipsis where I can view or download the yaml. If I “edit config” I get an error. I can choose that delete link but it doesn’t do anything.

From kubectl directly to the cluster, the nodes are gone.

This cluster is woefully overdue for an upgrade (running kubernetes v.1.22.9 and Rancher 2.8.5) but I’m not inclined to start that with two wedged nodes in the config.

Grateful for any guidance.
