Maybe there's some bug in 12.2 with event propagation when using ALTER SYSTEM, maybe a variation of what's described here:

https://blog.tanelpoder.com/2013/10/07/why-doesnt-alter-system-set-events-set-the-events-or-tracing-immediately/

... Although eventdump seems to show the event is enabled for the session too. Did you start session 2 before or after issuing ALTER SYSTEM in st?

If 12.2 happens to use the Multitenant config, perhaps test running the ALTER SYSTEM at the root CDB level...
