Username and line breaks

Hello,

I'm upgrading my Joomlasite to 3.3.6 and installed Komento instead of JComments, which I used the last years. I'm glad that I could migrate all the Comments in the new component. But instead of line breaks there are lots of < br / > in the text



The other problem is, that the real name is shown, even I chosed "username" in the configuration:



Only in the Komento Userfile the Username is shown.

Last but not least: Is it possible to link the Username with the CB profile instead of Komento Userporfile?

Can you help me, please?

Yours,
Jana

P.S.: Sorry, if my English isn't so good ...
