Blueprints event inheritance can't call parent function

Hi,
basically i have a master enemy classes with several On Overlap events defined:

I want to inherit this class to define several ennemies, and just changing their respective flipbooks references (stored as variable).
I use event overlap to trigger death and set the flipbook to the death sprite, than destroy the actor after a short delay.
I can call Parent: Tick, but i cannot call Parent: On Overlap Begin (Box).

Am i doing something wrong?

Ok nevermind, it’s fixed in 4.17 and events are also inherited, sorry for the inconvenience

Can You explain me what happened, I have a similar problem
