Hi,
In Easy Profile options try to set 'display format name' on username.

Thank you - but that is already selected. It correctly shows only the Username on the Profile Page. Its just the title of the page on the top of the browser window.

To resolve it I have hacked the /components/com_jsn/views/profile/tmpl/default.php file on line 15

from this:
$this->document->setTitle($this->document->title.' - '.$this->data->name);

to this:
$this->document->setTitle($this->document->title.' - '.$this->data->username);

Hi,
I had not realized,

we will fix in the next version.

The best way is

$this->document->setTitle($this->document->title.' - '.JsnHelper::getFormatName($this->data));

with this the change with Easy Profile Configuration

Thank you. I have replaced my hack with that. Works good...
