Hi,
I'm not sure if I understand it correctly. So you have the same one category linked in two menu items and one of them is set as homepage?

yes

press release is on main page listed as category list..
and in other menu "presss" i have press release..

and joomsef do not handle it.

helou, is there someone ?

i'm using languages joomsef

And is there any difference between the two pages? Since they link to the same category, JoomSEF automatically uses the homepage link for the other one too to avoid duplicate content (two different links displaying the same content).
Maybe you can achieve what you want, open the Manage Extensions page in JoomSEF, there click the Content extension, and there on the Common tab set Ignore multiple sources to No.
