WP Event Manager offers a separate section in the single event listing page named Additional fields that display all the fields that are created additionally using the Field editor.
It is not necessary for all the users to display this section on the single event listing page and hence adding the following code would help you disable the section automatically.
In order to hide the additional information section from a single event page, add the following code in the functions.php file of the child theme.
