OpenNebula 5.12.0.1 not resizing cpu in new vms

When i resize a cpu, i get success, but in affect nothing changes. not in the opennebula side and not in the vcenter side. this happens on all vms that i setup. must be something with the template, but i can’t find out what. imported vms seems to be fine.

memory, networking, virtual disks are all fine, only cpu can’t be changed
