Bug displaying Geopotential Height for GFS

[tempa]

When looking at 500 hpa wind and geopotential height layer turned on, the GFS model does not display the isolines correctly. Most times the lines are not updated when selecting a new time. However, it appears everything works correctly when using the ECMWF model. I see this on my computer using Edge or Firefox as well as on my ipad app.
