VS 2012 fails to deploy 2 instances of my WCF WebRole, only 1 instance is deployed.

Question

I have created an Azure Cloud Service with a WCF WebRole as usual, using Azure SDK 2.5.
At the time the CloudService has only one role.
The ServiceConfiguration.cscfg file defines that the role should have 2 instances.
I'm deploying the cloudservice using VS2012 SP4 successfully. The Role-VM starts successfully. The service works.
BUT there is only 1 role-instance of the service deployed instead of 2 as defined in ServiceConfiguration.cscfg.
WHY? There is no autoscaling in effect, autoscaling is deactivated. This was not a problem before. Why is there only one instance created for me instead of two?
I've got plenty of available CPU cores in the subscriptiontion, not a problem. 
Here is the relevant snippet of the cscfg-file:
<?xml version="1.0" encoding="utf-8"?>
<ServiceConfiguration serviceName="... some service name ..." xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceConfiguration" osFamily="4"
osVersion="*" schemaVersion="2014-06.2.4">
  <Role name="... some role name ...">
    <Instances count="2" />
    <ConfigurationSettings>
      <Setting name=" ... some settings ..." />
    </ConfigurationSettings>
    <Certificates>
      <Certificate name="... some certs ..." />
    </Certificates>
  </Role>
</ServiceConfiguration>

Hi Will,
it seems that there is a bug in VS2012 regarding the number of instances in different ServiceConfiguration.cscfg files?
I happen to have two ServiceConfiguration.cscfg Files, one for PROD ServiceConfiguration.PROD.cscfg, one for DVLP ServiceConfiguration.DVLP.cscfg from which I deploy.
The DVLP.cscfg defines 1 instance, the PROD.cscfg defines 2 instances.
If I set the number of instances in DVLP.csfg also to 2, then the deployment on PROD produces 2 instances. If I then Switch back to 2 instance
in DVLP and then deploy PROD again I get 1 instance there again.
This did not happen with previous Azure SDKs.
Best regards
