Only some Favicons are visible

Hello,
from all my ~50 feeds only three are displayed with favicons. The favicons-folder also has only three .PNG files.

Examples for working feeds:

Examples for non-working feeds:
http://feeds.feedburner.com/DilbertDailyStrip
http://feeds.feedburner.com/wulffmorgenthaler

Is there any possibility to manually ad icons?
I'm using selfoss 2.7, BTW

Thanks,
Phil
