Station plot pressure trend

[Northseaweather]

I am evaluating the software, so still find my way around.
From the station plot I am only able to see the pressure trend when printing using the NMC font. When using the TrueType font, I get a value for the pressure trend but no indicator as to whether it’s falling or rising. Is this simply because I am using an unregistered version. Have not been able to solve this from the help file.
I’m old school, when we would bind a blue and red pen together to plot charts. So do appreciate the use of colours for rising and falling.

Have checked the metro.ttf included with the package. There are no glyphs for pressure trend or cloud types.
Have downloaded both the metro-old and meteor-new from the website. Same problem, neither of these files contain glyphs for pressure trends or clouds.
