Steps to reproduce:

Prepare the environment:

• Prepare two eZ Publish 4.7 installations, fully patched. One will be your source server, and the other will be the target server;
• Install eZ Content Staging 4.7.1 on both installations. More details here:

https://doc.ez.no/Extensions/eZ-Publish-extensions/eZ-Content-Staging/eZ-Content-Staging-1.x/Installation

Note: when installing eZ Content Staging 4.7.1 in the source server, make sure to use on contentstagingsource.ini.append.php:

TransportClass=eZRestApiEmbeddedClientStagingTransport471

Reproduce the issue:

1. Source & Target: go to Setup/States and create a new state group with 2 object states, as follows:

Identifier: state_for_test
Name: For test

Object states in group:

Identifier: true
Name: True

Identifier: false
Name: False

2. Source: create a test content (used an article), and set "state_for_test" state group to "false". Publish;
3. Source: sync article to target instance;
4. Target: check that the content object has been synced and check the state: it has been lost during the sync, as it is set to "true".
