I can’t add alert rules from the collection WebGUI

I’m having the same issue on 3 installs. I can’t add rules from the collection. Choosing select the window will disappear but no rule is added to the list.

I have tried Chrome, Firefox, and Edge. All 3 are the same.

The validate config passes with no errors.

Today, I tried adding an alert template again from the alert collection and receive a messages that states;
“Failed to process template”

Cisco PSU status failed sensors.sensor_current = "8" && sensors.sensor_oid = "."

when click “select”, no action takes place.

This is working again.
