Anyone else getting issues with height fields that get stuck in the viewport?

I'm having this issue where I use some volume visualize node to look at the data in a heightfield layer and it ends up duplicating my heightfield in the viewport and won't go away even when I toggle the visibility flags on the sop nodes or even the geo level nodes.

I end up having to restart houdini to make it go away. Happy to file a bug report but maybe it's user error and I'm missing something?

Thanks!
