[SOLVED] Typography - Numblock shows no numbers

Hi,
found not yet an answer, well lets see if someone has an idea.

I have created new articles with the codes on the
https://demo.gavick.com/joomla25/university page.

I'm looking forward to the NUMBLOCK.
When i enter the code, it does not work.
Other typos work fine.

I have tried to copy the html content from the 'typography' article to my new created article - no success.
the Numblock will be showed as in the picture below.

What i'm doing wrong?

many thanks for help.
regards,
AF

add:
it should look like this - green.

Ok fixed it.
I had to choose no WYSIG editor. With the tiny it seems not to work.

thanks anyway.regards
