This issue needs to be escalated to our developers, kindly create a copy of your site and provide a link to download it. You can use the Duplicator plugin (https://wordpress.org/plugins/duplicator/).
The plugin will create a package file that you can download then upload again to Google Drive or Dropbox and share the download link in the next reply which I have marked as private. Then I’ll escalate this issue to our developers.
Hmmm This means I have to change all items with slightly different notations, which will look unprofessional so this is not my preferred solution... What else can we do?
And this just use to work normally until some weeks....
