Thank you for reply.
We are using Firefox (on 2 PCs), did clear the cache, web looks still the same.
Removed only “Assign Font” (to preserve API Key), not font itself from “Upload Fonts” section.

Printscreen with marked errors and correct spec. chars (for easier comparation): http://goo.gl/4YIUAT
Thank you in advance.
