K2 - (m) social - quickstart - problem with link

I have a relevant problem with (m) social template.
I used the quickstart, and now i'm setting up my new menu entries.

When I create some new entry, using the friendly url of joomla, the URL are something like:
http://www.sharingalicia.org/index.php/ ... 0/asociate

where all this part shouldn't be there, and it is costant in every URL.
index.php/k2-users/k2-extra-fields/k2-extra-field-groups/k2-media-manager/k2-information/2014-08-21-11-46-20/

If I take out the friendly URL, the result is not so nice too:
http://www.sharingalicia.org/index.php? ... Itemid=889

I have benn checking in:
joomla configuration
k2 configuration
moving menu items (sometimes I have a better URL moving the menu entries, but I lose the website map in this way)

Had had the same problem?

I have this problem with k2 items and with joomla articles... I mean this string it always appears:
k2-users/k2-extra-fields/k2-extra-field-groups/k2-media-manager/k2-information

And to be honest... I really don't know why...

Thanks in advance

Hi

You must have this menu items with aliases stored someplace. Either it is in menu items or categorie's names. I'm afraid there is no other way than to create a better menu structure. With a landing pages for all articles (simply a K2 category type menu item). You will need to recreate Your site map, becuase links should change then.
