Hello Karsten,

Mapbender is quite old ;) Release date: 04.02.2016 

Best way is to update an existing Mapbender installation instead of 
copying an application.

Have a look: https://doc.mapbender.org/en/installation/update.html

Maybe for your workflow it could work:
* copy & import your application
* open map-Element and check the selected layersets -> save it
* open layertree -> save it
-> we had some changed concerning layersets, so maybe the element has to 
save the new configuration.

Best regards
