Unable to edit custom Synthetics Alert in Kibana

Elastic Cloud 8.15.0.

I am creating a few custom Synthetics rules using monitor.tags in the Action query to do some specific alert routing by environment. However, I have an issue: When I create a custom Synthetics alert, its behavior is like the default Synthetics alert - I am unable to go in and edit the rule that I just created.

I suspect that this is a bug, but I just wanted to confirm that I'm not missing something before I report it.

Edit

When I go into the Monitors page, then select Alerts and rules->Monitor status rule (see screenshot) it selects the rule I just created, not the default:
