Struggling with an extremely simply Node Type validation for preventing deletions and renames

Hi everyone,

I thought this would be such an easy thing to do, but for some reason, it is not working. I have created a Node Type-level validation that has trigger actions of Delete and Rename. The expression is simply "Return False", which according to the documentation, would trigger the validation. I've also tried True though.

The validation is enabled and on the correct Node Type, and the Rename validation does work. But when I go to delete the node, the validation does not trigger. Any ideas why this is happening? It doesn't seem to make any sense
