Maybe someone has any idea?

I did not touch or change or install anything. All of a sudden the digits except for "course" are gone. All other panels like for 787 and a320 etc are ok, except this one. I tried re-downloading the panel - no change. All the gauges, xml files, etc are in place...

 

 

Looks like a font may have gone missing..

all the xml files point only to Arial font. It was already present obviously, I did a reinstall - no effect
