People, Trees and cars move all around

I posted this last week and the post has been removed

Any object I place in LumenRT moves.  I mean moves from where they have been placed.

If I change anything to the model it causes all work in LumenRT to move

I have tried this on two different machines with two different projects and the problem is consistant

The last time I was in the project and all of a sodden anything I placed was 300' tall giants in the model

I deleted my one giant and left the model only to return with a 1000; giant I deleted to only find everything had moved

This is a much more powerful machine and graphics card and started to work better as the actors worked better with live shadows I don't see on the other machine.

But nothing works here as I can rebuild everything every time I use it.
