Fields in Insert/edit link popup

Hi,

When editing a link in the WP Admin, there is a native WP popup window that appears with fields such as URL, Link Text, Link Title etc.

On that popup I have a line & 2 checkboxes added by the plugin. They are:

Use in Schema Markup
– about
– mentions

These text line & checkboxes overtake and hide the searchbox that appears below which lets us search a post/page.

What is the setting to get rid of these text & checkboxes from appearing on the popup?

Thanks.

The page I need help with: [log in to see the link]
