I've tested it and I can't seem to replicate the issue on our sandbox site here hidden link .
This is the test page hidden link
Could you try replicating the issue over there?
If the issue continues, I will need to closely examine your website. Therefore, I will require temporary access (WP-Admin and FTP) to a test site where the problem has been replicated, if possible. This will enable me to provide better assistance and determine if any configurations need to be modified.
Please note that it is important to have a backup for security purposes and to prevent any potential data loss. You can use the UpdraftPlus plugin (https://wordpress.org/plugins/updraftplus/) to fulfill your backup requirements.
Your upcoming reply will be treated with confidentiality and will only be visible to you and me.
✙ To resolve the issue, I may need your consent to deactivate and reactivate plugins and the theme, as well as make configuration changes on the site if necessary. This emphasizes the significance of having a backup.
