I am using SPPB 5.1.9 and i successfully uploaded a font "Vinio" but when i try to set the font in any of the addons, it does not show in the list of available fonts.

Screencap show the uploaded font:

Is this a bug or is there a limitation on the number of fonts? I have provided the site diagnosis.
