Here is the ticket. Please create a backup file of your site and database then share it with me. I will try to restore your site on the local host and investigate the issue. Your next reply is set to private to share the info.
You can use this plugin to create the backup: https://wordpress.org/plugins/duplicator/
I've downloaded the database and website files but it is a large DB file and complicated setup. I'm not able to import the database and restore your site on my local host.
Checking the translation page in the admin area, I see it occurs because of the order of flexible layouts is not synced to the translation page. Please try to edit the field group > set the field preference of all fields: Flexible content, Group, Repeater to "Copy" to keep the same order in the second language.
Then make a small change to the page title > Save changes > Update the translation and see if it helps.
❌ IMPORTANT: Please backup your database and website before proceeding ❌
If not, please copy your site into a staging site then remove some unrelated plugins and content to reduce the data size and create a backup file with the plugin Duplicator or All-in-One WP Migration then share the backup file and staging site credentials (wp-admin and FTP). Your next reply is set to private to share the info.
After restoring your site on my local host, I changed the Flexible Content field preference in the Block field group to "Copy" > Save changes.
Then edit the page > Make a small change to the page content > Save > Update the translation page and that fixes the issue. Can you please apply this workaround on your site and let me know how it goes?
I also recommend changing the preference of all fields Flexible content, Group, Repeater to "Copy" to keep the same order in the second language.
