Spawned objects intersecting each other - how to prevent it?

[gphysono]

I'm having a issue where spawned objects are frequently intersecting each other, despite the prefab having a box collider and the spawners bounds extents set high.
I've attached a screenshot showing what I'm getting. The first image is what I'm spawning, the second image is the spawner settings. 
I'd like to spawn objects with a lot of space between them. 
I'm using Unity 2021.3.101f and Gena 3.5.5-c5
Any advice and guidance is appreciated.

Can you try and increase the bounds extents?

So two things with this you need to increase the bounds extents and you need to modify the prefab to set it on one of the Gaia layers or create your own layer for it. 
Then change the layers in the spawner to match that for the collision.
