Remove Social Fields in Job Submit Form

Hi!
hoping someone can point me in the right direction. I’m using jobify theme with wp job manager and I wanted to rem out some fields in the job submission form. (File: class-wp-job-manager-form-submit-job.php) I was able to find and rem out twitter, video and company website, but NOWHERE can I find the Google+, Facebook or Linkedin on here. Very odd…you’d think it would be in the same group as the rest but it’s not. I’ve scanned and searched the code several times thinking I must be crazy, but indeed, it’s not there!?

Inspecting the code on the form, it clearly shows there the Company Information fields which have the fields I want to edit, but not sure what file that’s in and if it will affect any other parts of the site.

I know enough about php to be dangerous. If someone can enlighten me on where these fields are, that’d be great. I don’t want to pay for the plugin that can accomplish this, BTW.

Thanks so much!
