Endpoint acts like it has not been updated/ignores changes

Hello, I have an email endpoint that I made changes to over a year ago. I changed the email address to send to and added an additional sentence and field in the body.

Those changes are not reflected when the endpoint is called. If I clone the endpoint, and make some superficial change (since the real changes I made are already shown on the endpoint inputs), that new cloned one continues to send the old body to the old email address.

If I create an entirely new endpoint, and set it up exactly like the old updated one, with a new ID of course, I get the desired result reflecting the updates.

I don’t need any help since I found a workaround, but it seems like the original endpoint is stored somewhere that can’t be updated despite the UI acting like it’s possible to make changes to existing endpoints?
