K2 items loose formatting in front-end

Hi,

using Tiny or Jce editors, when I look the K2 item in front end it is not formatted, without heading1, 2, 3, bold, italic, paragraph, etc....
I use Joomla 3.4.1 and K2 incluse in you Blog template v.2.6.9. Using normal Joomla Article (instead of K2) there's no problems.
Another problem I have is that I can't edit contents from front-end: the edit icon doesn't appears.
Thanks.

1.) The formatting is editor thing. You have to add the css to your Editor >> Google Joomla Editor CSS
2.) K2 has no more options to edit articles in frontend. Switch to "protostar" default template and there is no more options to edit K2 articles

Thanks for quickly!

For editing in front-end... OK, but it's a pity in a blog site.
For the lack of formatting in front-end, what do you mean with "Google Joomla Editor CSS"?: to search in Google how to set a custom CSS for the editor (ex. JCE)? An why, if a make a Joomla article (not K2), there's no problems?

Thanks.
