Cluster Cache Jira DC

I am developing a plugin for Jira Data Center which uses Atlassian Cache. I followed this article:
https://developer.atlassian.com/server/confluence/atlassian-cache-2-overview/
The problem is that my cache works fine locally but it does not want to replicate along Data Center Nodes. I am creating serializable classes but it still does not want to replicate. I am definately missing something. What can be the problem? Maybe someone has an example.
If i check Cache to different Node, it always epmty

  @Inject
    public SettingsServiceImpl(ActiveObjects activeObjects, CacheFactory cacheFactory, @ComponentImport CacheManager cacheManager) {
        this.activeObjects = activeObjects;
        this.cacheSettings = new CacheSettingsBuilder().remote().replicateViaCopy().build();

        this.cache = cacheManager.getCache(SettingsServiceImpl.class.getName() + ".cache", this::loadSettingFromDatabase
                , cacheSettings
        );


    }



private Setting loadSettingFromDatabase(@Nonnull String name) {
        Setting[] settings = activeObjects.find(Setting.class, "NAME = ?", name);
        if (settings.length > 0) {
            SettingImpl settingImpl = new SettingImpl();
            settingImpl.setName(settings[0].getName());
            settingImpl.setValue(settings[0].getValue());
            return settingImpl;
        } else {
            log.info("Setting '{}' not found in database", name);
            return null;
        }
    }

}

I think in general Atlassian does not recommend using replicateViaCopy

I’d suggest having a thorough read through this page, as there are some non obvious issues that can arise with some cache configurations: Jira DC Cache Replication - dev tips & tricks | Atlassian Support | Atlassian Documentation

Specifically you may be running into issues documented in the “Non-sense caches” section.
