System constraints triggers shouldn't appear at all if you didn't select
the "Show system objects". They never should appear in the SQL pane of a
table description for example.

User constraints triggers should always appear.

The fact that system constraint triggers appear wasn't done on purpose.
As a matter of fact, this is a bug.
