We recommend that unless you need to store CV/user profile locally
You don’t use WP Job Manager Applications and Resumes But use the native Matador application form
Leave the application method as a default for the Matador Form
Otherwise, if you either the WPJM Applications or WPJM Resume Manager there form will show and Matador will sync the data from the active plugin.
If you have both installed you need to pick which data source to sync with Bullhorn with this control in the main Job listings settings
You will find a matador tab in the setting of your selected source
