cite and citelink not working

Those aren’t a standard part of WordPress. What are you using to provide or manage the custom fields?

No, what is the name of the plugin that provides the functionality you’re referring to?

WordPress does not have “cite and citelink” by default.

Ok, I recommend asking at https://wordpress.org/support/plugin/feed-wrangler so the plugin’s developers and support community can help you with this.

Or, given the age of that plugin, perhaps finding an alternative would be better.
