Error when creating a BlackList

There is a variable [$page_name = $data['page'];] on bsk-gravityforms-blacklist/classes/dashboard/list.php that is preventing the plugin from creating new blacklists or deleting elements from the list, this variable is not even used in the function bsk_gfblcv_save_list_fun function.

Our CI/CD pipeline reads from wpackagist and is causing failures due to this variable.
Could this variable be removed and have a new version published?
