BE2014 SBS - License Count Client OS as Server

Hello,

Using BE2014 SBS Edition on a SBS2011.

We are getting the "Warning" that we are Backing Up more Servers than we have Licenses for...

In the MouseOver the "Servers" are Listed and one of them is a Client. (Windows 7 OS).
(But it is running on a HyperV System like the SBS2011).

Is that a Bug or is there a way we can change this?

Thanks and best Regards
Danny
