problem with classified plugin

hello i just installed plugin “acategory-dropdown-list” to select category as drop-down in post.

but in classified when i add new classified from admin menu “acategory-dropdown-list” plugin works fine , but when i post new classified from buddypress menu it does not work…

so what to do, is it possible by edit classified/uifront/buddypress/member/single/classified/update-classified.php ? , if yes then what to do.
