Tick Interval on child actor / Set Actor Tick Interval - not working?

I have a project where this works just fine.
Made a new one, create an actor with a custom tick interval, and it keeps on ticking every frame instead.

Any ideas on what project settings I may need to tweak ?

didn’t figure it out. Delete the project, made a new one. All is aces.
must have been a rogue .ini setting or some missing base file…
