Rhino 6 Clipping Plane Block Bug

When using clipping plane to cut section through a block model, the thicker cut line sometimes appears, and sometimes it does not. The solid geometry also does not fill correctly per settings in options menu.

When the block is “exploded” the clipping plane acts as it should, and the thicker line is visible, and the solid geometry is filled correctly.

Has anyone found a solution or had this issue? We are trying to avoid a solution that requires 2d drafting such as make2d, section, or hatch command.

In the images below, we show the blocks “intact” and the block exploded for reference.

Hello - of you could post or send us the model a t tech@mcneel.com, we can have a look.
