this question has answer here:

since adding ios8.3 or 8.4 simulators, device list in xcode 6 filled udids instead of ios version. adding 8.4 sim new xcode 7 beta seems have created similar issue.

enter image description here

in device list (window > devices) there multiple devices same ios version.
after deleting each duplicate device able restore order devices dropdown. seems bug ios8.4 sim, had duplicates of ios8.4 devices
