All saved modules have moved to Saved Templates

A strange bug has happened on my site, all the saved modules/columns/rows are appearing under the Saved Templates in the editor, while on the WordPress Admin they are currently under Saved Modules/columns/rows.
This means I can no longer add a saved module such as a button because it doesn’t have a row to support it when appended as a template.

Strangely there is only 1 saved module/column/row which appears correctly in the editor and works properly, even new modules go into the Saved templates.

This does not happen to my sites twin staging site which has the same plugins.
