Net Cull Distance Squared - How does it work?

Sorry for triple bump, but I still can’t get this to work at all.

I decided to do the simplest test possible. Here’s what I did… I migrated the ‘Content Example’ relevancy chest - it worked 100%. So, I simply copied what it was doing. Top is mine:

Inside both rep notifies are simple ‘Hello’ prints. My actor has a net cull distance of 4. It should be irrelevant to all clients… right?

When I overlap the chest, only the server and the overlapping client print. When I overlap my actor, EVERYONE prints.

I’m at my wits’ end with this, I really don’t know what’s wrong. Both actors have the exact same settings, except for my actor having 4 for the cull distance. Left is mine:

EDIT: Of course shortly after posting I figure it out… Here’s it working:

The FX only spawn is the client close enough, too
