Open polygons in certain airspace

I’ve noticed some issues with certain airspace having open polygons. For example, here is a side-by-side with Skyvector showing the R-4808S airspace. In Navigraph Charts the lower border of the airspace is not rendered. Also, when you place a marker inside of it the airspace is not listed.

This is near the Beatty (BTY) VOR.

Hi,

Thanks for the report. We’re investigating!

Regards,

Stephen
