HMC 8.1 Virtual Storage Management GUI Buglet!

We have the new HMC 8.1 code stream to manage the POWER8 machines. It also manages the POWER6 and POWER7 machines but not POWER5.
I find the HMC Virtual Storage Management panel very useful and saves me time for assigning Shared Storage Pool (SSP) space to virtual machines (VM's) and automatically doing this for Dual VIO Servers without having to log-on to the VIOS servers at all. It is also good for assigning virtual DVDs to VMs to boot and install the various operating systems, AIX, RHEL, SLES, Fedora, Debian, etc.
Unfortunately, the new HMC code displays the Shared Storage Pool data incorrectly. It is a minor distraction rather than a major issue. We can just ignore the extra lines - any lines with a size column of just "MB" should be ignored. I think it is caused by changed in the VIOS command output that the HMC can't cope with. I expect the next HMC update (expected in a few months time) will correct this or is it a VIOS command issue!
The contents of the Red Box are a mixture of command Header Lines and the names of Shared Storage Pool Snapshots which were previously filtered out and not displayed. Please ignore then.
As I am using PowerVC on top of the Shared Storage Pool it is interesting because it is showing some details not normally visible on the VIOS CLI like PowerVC using Snapshots for Shared Storage Pool Linked Clones. Each PowerVC created VM that is Deployed from a "master" Deployable Image is actually a Linked Clone i.e. they are sharing the same SSP chunks (think 64 GB) as the original Image until a chunk is written too. The greatly reduces the disk space used - and in addition to the Thin provisioning that SSP can offer.
This can be seen also with the information at the end of the list:
Here we see the PowerVC Images, for example, "vol
