Ok. The first attach is the set up of URL. I expect that joomsef rewrite the url when the page is linked.
I have tried two ways:
First way:
The 2nd attach is the set up of the plugin of joomsocial for joomsef. In this case the 3rd attach shows that the link is correct but not in sef mode.
Second Way:
The 4th attach is the alternative set up of the plugin joomsocial for joomsef. In this case the 5th attach show the link is INCORRECT and also not in sef mode.

I've searched the error in the URL list management, but I've not found anything of interesting.

Does anybody can help me to solve this error ?

Thank so much !

Hy. In case of JomSef enabled the links bring to other pages respect of correct pages, instead when JomSef in not enabled, the links direction are write. Why ?
