how to change the way page title appears on vendor page

whenever i go to vendor page the it shows the name in title bar as ” name_of_vendor/WCMp Vendors/website_name “. I want to keep just name_of_vendor/website_name. I tried to do it myself and commented the name in class-wcmp-taxonomy.php but after that it showed as name_of_vendor//website_name. Please tell how can i achieve this.
