Hi All, I'm having a similar issue as everyone here but for me my ghosted devices showed up after i ran os x in a virtual machine on my mac. I only have 1 macbook pro, and 1 iPhone 5. I was able to successfully remove old iPhone references through find my iPhone and iTunes. However the two ghosted devices for devices that don't physically exist show up in my devices under settings. The problem here is I believe it broke continuity as well. since it quit working after this problem showed up.
The macbook pro expects the handoff and continuity features to be there , the iPhone doesn't recognize the features even exist. however sees other devices on my network such as Roku player etc. For me the features seem to turn on and turn off very suddenly and randomly.
here is a screen shot of what's going on. Also keep in mind the ghosted devices don't even show up as a genuine device.



I know I posted a few pictures, but I wanted to show details of the exact issue since it's different then most. The two devices with the iFrog-Media name are the real functioning devices. How the virtualized iPhones showed up I have no idea, i never used the iPhone with vmware virtual machines of os x.
Anyway if anyone has any ideas let me know thanks!
