Dear Anikó,
I'm afraid that this question is so project-specific that only someone who knows the project can really answer it.
I assume, that it isn't a release issue (normally you have to release a node, before changes can be deployed to the live site).
Maybe this will help you: Just search for the name of the recruiter. Can you find it in a global content area or in a dataset record? If so, you may have to make the appropriate adjustment there.
Important: Since I don't know the project, I can only guess what might help. You can only get a really meaningful answer if you contact someone who knows the project or can look at the project together with you.
Best regards
Holger
