[ORD R9] Contours in a Terrain Element displaying Minor Contours on Top of Major Contours and Showing on Top of Major Label Text Masks

I never noticed this before so I don't know if this is a knows issue. We have our Element Template defined to display only Major Labels and they use a text style with background masks. I was seeing lines running through the labels and the dashed lines used for both contours sometimes appeared solid. As I experimented with levels and other things, I turned off the major contour level and noticed that there was no gap where the major contours were now missing from the display. Checking elevations, I saw that I was getting minor contours displayed on the major contour elevations. Our major contours display white and with a greater weight and our minors display in red.

Is this possibly a known issue or are we missing some setting that would prevent this?
