System missing from Entity Debugger

I have a system with the [DisableAutoCreation] attribute. I manually create it with:defaultWorld.GetOrCreateSystem<MySystem>();
It is updated manually by calling mySystem.Update() from FixedUpdate.
The entities appear in the debugger and I can see chunk utilisation etc. It all works fine in the game.

Is this a known problem with Entity Debugger? Other auto-created systems appear as expected.

That has been answered here

Thanks. At least we can see the entity data (although not the system that generated and updates them). With a bit of digging the system also appears in Profiler.

When I select the correct world, I’d have expected to see my system - but I guess that is a design constraint that will make debugging systems a little more challenging.
