Child actor box extent values not updating

Hi guys,

I’m noticing some odd behaviour trying to use child actors within blueprints.

I essentially want to create a markup system, the Parent BP has a static mesh and then additional child actors can be added to create trigger boxes around this static mesh.

The child actors are C++ subclasses of the TriggerBox. The issue i am having is that when i add a child actor into the parent BP in the editor, i can only change the “Box Extent” values once. Any additional attempts to change this value does nothing to the trigger box. This is highly annoying as i need to be able to add multiple child actors to this parent BP and modify them individually.

Notice the values below are different but the box remains the same. Does anyone know how to fix this? (the images below show a box with extent 200 even if it is set to 40!


Does no one know why this is happening? Not a single person has had this issue before? Any help would be greatly appreciated.
