Saving section with 'Administrator' & 'Editor' accounts completely erases whole content. Only Super Admin accounts can make changes

Hi, we are encountering an issue where if any user account on the website with less than Super Admin privileges (e.g. Administrator, Editor) edits something in cornerstone (for example a component or menu), upon clicking “save” the entire content is erased.
When editing imags or text on a page in cornerstone the accounts seem alright, however this is making us understandably nervous as anything previously that has been erased has been erased instantly in all languages and has been unrecoverable.

This is occurring on two of our sites
mylifehouse.com/tokyowest and mylifehouse.com/yokohama

Please see a demonstration of the issue here: https://www.loom.com/share/e9b9e6cabc3f4a9188916da9a9b8f45e

Kind Regards,

Hello @lifehouseglobal,

Thank you for the inquiry.

That is an odd issue. We may need to log in to the site to properly check the problem. Please create a test page and provide the login details for both the admin and editor accounts so we can test them. You can include this info in the secure note.

Best regards.
