Plan Region Extras

[studio3p]

I'm encountering a rather annoying phenomenon with the new Plan Region feature. Within the Plan Region zone the View Depth seems a bit skewed. I'm attaching a few images that shows the problem. The region displays information below the view depth I've specified - you can see this in the concrete slab pattern to the left of the door. I've checked the View Depth settings of both the main view and the Plan Region, and the Primary Range>Bottom: and the View Range>Level: are set to Associated Level.

Any ideas?

I have the same errors.
It seems that all parts of the plan become 'transparent' as if the wire frame view has been switched on.
This does not seem to happen immediately but only if I edit the plan regions.
Even deleting the plan regions does not seem to immediately fix the problem.
In my case, I have columns that are raked and I need to show them on the plan at floor level - not raked - but the rest of the plan as standard.
