Composite disk double counts

Using version 2.3.7 from Fedora 24 repositories.
Also noted the same problem on F22 and F23 releases.

The composite disk graph reports double the data
rates of the individual disks.  This is most easily
seen when one file system is heavily used.

I'm using 4 drives, 2 SSDs and 2 HDs.  Each has
4 partitions.  Most of the partitions are then
used as physical volumes for LVMs.

In the configuration panel I can display the
partitions (ex sda2) and/or the LVMs (ex dm-8).
My supposition is that both the partitions
and the LVMs are added together to get the
composite number.  This would result in
counting the same activity twice.
