GTN650 airspace dashed not solid line

[RO13FLY]

Hi all

I have a Garmin 650 and the aviation database is updated by someone each month. After a recent update, most airspace is shown as dashed lines which are really difficult to read and made worse because it looks like the dashed lines have dashed shadows. It was much easier to understand when the lines were solid. I have looked at the settings and can't see anything obvious that was changed in error.

Anyone else had this issue? Even better, anyone got any advice how to change it back to a single solid line for the airspace boundary?

Thanks
