Materials get reset in USD Composer every time I make a change in Rhino

I’m still getting used to Omniverse so this might be a basic question. I created a simple block in Rhino and then live linked it in USD Composer. I added a material to the block in USD Composer. Then if I modified the block in Rhino it would remove the material in USD Composer. Doesn’t matter if I move the block, add a chamfer to it, increase the size, etc. Any modification removes the material. Is this normal behaviour or is there something I’m doing wrong?

Someone replied asking me to upload the log from Create but it looks like the comment is gone now. I’ve uploaded it now. Hopefully someone can have a look.
