Splunk App for VMware: Why have three license files installed on our license master. Is the app supposed to sum them together?

Hi. We have three license files (1x5GB 2x20GB) for the Splunk App for VMware installed on our license master. I assumed that the VMWare app will sum them to 45GB, but instead I receive only 20GB. VMWare App -> Settings -> App License Status What happens here? Thanks Markus
