Wordfence and Elementor: 403 server error

Hello, I’m writing you regarding a website I manage. The website is running the latest Wordfence and Elemetor, Astra Pro and WordPress 5.3.3

Recently, a user reported being unable to edit a page with Elementor and reported a 403 server error. After investigating, I found it may be Wordfence blocking some actions.

So, first thing I put the firewall in learning mode and then investigated further. I found the actions being blocked by Wordfence:
User left /wp-admin/post.php?post=1818&action=elementor and was blocked by firewall for XSS: Cross Site Scripting in POST body: actions=%7B%22save_builder%22%3A%7B%22action%22%3A%22save_builder%22%2C%22data%22%3A%7B%22status%22%3A%22pub… at /wp-admin/admin-ajax.php

User left /wp-admin/post.php?post=1831&action=elementor and was blocked by firewall for XSS: Cross Site Scripting in POST body: data=%2Fwp-content%2Fplugins%2Fnex-forms%2Fjs%2Fnexf-onload-ui.js%3Fv%3D.5%26… at /wp-admin/admin-ajax.php

I whitelisted these actions. Are there further actions to take, to prevent similar issues to happen again?

Thanks!
