AEMaaCS - Context aware configurations for specific run modes

I am trying to add a cloud configuration such that it is specific to run mode 

Followed the doc  and section to set up context aware config per runmode

https://experienceleague.adobe.com/en/docs/experience-manager-cloud-service/content/forms/integrate/use-form-data-model/create-form-data-models

The config is picked up by instance in felix console and is stored under config.author

But this is not syncing to the configuration that i assume should have been reflected at?

I am trying to use a form model with data source and data for data source is below

// Configuration created by Apache Sling JCR Installer
{
"enabled":true,
"description":"Test a Connectivity",
"overrides":[
"cloudconfigs/fdm/test-connectivity/resource=\"hello123\""
]
}

I expect that refreshing the node under the config /conf/<conf-name>/settings/cloudconfigs/fdm/test-connectivity/jcr:content the property "resource" should have updated to 123?

Kindly let me know if i am missing something
