Steps to reproduce

1. install lightmodule
2. import website.master.yaml in website
3. create two live copies (or even 3 like me, see image-4.png)
4. delete the c24 page in every copy (so that you emulate the first creation of the live copy of that page)
5. create live copy on c24 (see image-5.png)
6. select all the copies (see image-6.png)
7. after creation it looks like image-7.png
8. check jcr (in my case master0 live copy has a wrong header)

Expected results

All copies are generated with the same structure

Actual results

Some copies are adding an extra node

Workaround

No

Development notes

This issue has been detected in three different use cases, but all of them related to complex fields.

• forms (component with area parallel to complex field)
• content carousel (component with area parallel to complex field)
• accordion (component with area parallel to complex field)

If we has 3 copies, it has been detected that copy0 and copy2 are including this extra nodes:

        'header':
          'jcr:uuid': '75180338-5a39-46a4-80df-0d4c1ad65460'
          'mgnl:removeIfEmpty': true

Exports from master and the 3 copies can be found attached in the ticket.
