When saving factory configurations using Instance Settings, it adds the "companyId" attribute which causes it to appear in Instance Settings rather than System Settings. However this is not included when you export, causing the configuration to migrate to System Settings upon import.

Steps to reproduce:

1. Create a factory configuration using Instance Settings
2. Export it

 Expected result: File contains the "companyId" property

 Actual result: File does not contain it
