Duplicate simulators displaying in Xcode 8

Don’t know if this is the best place to add this question but here goes.

I downloaded Xcode 8 and I noticed it’s displaying multiple copies of all
the simulators in the dropdown list of possible simulators.

How do I get rid of all these multiple copies and why are multiple
copies displaying?

Thanks,

Gary

Disregard this question. I finally got it working. I deleted all older versions of
Xcode and Xcode 8. I downloaded Xcode 8, again, and the simulators
registered properly!
