Ubuntu Condensed not working on Windows in Graphs

[feireislova]

I have a problem with Ubuntu Condensed not working on Windows in some graphs in my rmarkdown. Although windows does registrate the font, the R also does and the rest of the document works with the ubuntu font nicely. Would you have any suggestions what to try, please?

I'm afraid that without any code to see I can not be of much help
