Description of problem:
When cloning a PVC of 60GiB size, the system autofills the remote size to be 8192 PeB. This size cannot be changed in the UI before starting the clone.

Version-Release number of selected component (if applicable):
CNV - 4.14.0

How reproducible:
always

Steps to Reproduce:
1.Create a VM with a PVC of 60Gib
2.Power off the VM
3.As a cluster admin, clone the 60GiB PVC

Actual results:
The system tries to clone the 60 GiB PVC as a 8192 PeB

Expected results:
A new pvc of the 60 GiB

Additional info:

This seems like the closed BZ 2177979.

I will upload a screenshot of the UI.
Here is the yaml for the original pvc.
