On your "Blog settings -> pick a blog -> General" subtab you have selected 'Days' for 'Display unit'. That is what makes that little bit show up in the title tag.

Probably nothing to worry about unless it bugs you. If it bugs you then you could change that selection to 'posts' OR you could hack a core file. /inc/items/model/_itemlistlight.class.php around line 1130 should be this (in v246!)

{ // We are going to limit to LAST x days:
	// TODO: rename 'posts' to 'limit'
	$title_array['posts'] = sprintf( T_('Limited to %d last days'), $this->limit );
}

Change it to this

{ // We are going to limit to LAST x days:
	// TODO: rename 'posts' to 'limit'
	// $title_array['posts'] = sprintf( T_('Limited to %d last days'), $this->limit );
}

OMG..u help me with the simple solution!!

actually, i change the properties to Display unit to days instead of posts..
