Rename VM in Hyper-V and Failover Cluster

Hi,

I'm trying to rename a VM, and I've succeeded in all Fields, except on the name in the summary of the failover cluster (Zsap03 is the name I want and that is appearing in the menu and everywhere, and it is appearing Zsap03V1 on the virtual machine summary)

How is it possible to change it?

Note: I've changed on the Hyper-V Manager, on the failover cluster properties of that VM and also on the settings. I can't find anything else to find.
