Describe the Bug

Issue

When you have multiple locales and required localized fields, the orderable functionality breaks.
This happens when you create documents in a locale that is not the default and try to reorder.

The reorder operation updates the default locale, which will be empty in this case, and fails because the required fields are not filled in

Error in UI:

Actual error in terminal:

Reproduction Steps

Reproduction

I added a reproduction with the blank template. The following steps need to be taken to see the issue:

1. Switch the locale to French (or any non default language)

2. Create multiple posts for that locale

3. Go to the list view and try to drag.
   You will get the following error:

But the actual issue is hidden in the logs:

It checks if the Title & Content are valid, which they are for the French locale, but they are not for the default (English) locale, so the operation fails
