This is something we are experiencing when creating a dynamic macro in a confluence page. Curious if this is something that affects third party connect add-ons in general.

• create a dynamic macro for a third party connect add and save it using AP.confluence.saveMacro()
• edit and save the macro again.
• an additional macro is created. Expected result is that a single macro is updated.

This only happens if the macro is on a draft page. Once the page is published it is no longer an issue.
