Terminus-fond fails and shows empty box instead of a proper bullet in the 3rd. headline iteration.

[herop]

Your approach and the use of config.org was an eye-opener.
I actually use your config files. :-)
One thing bugs me: Even though I installed TerminusTTF on windows, the third depth of headlines has an ugly empty yellow box but NO Icon.
Please help me out.
Thank you in advance and have a great day,
Jochen
