I had the same problem today, but I found the solution for my case.
There must be a bug in the Studio that makes you cannot CHANGE the alias in the alias field on the Run Configurations (well, you can change it, but it recovers the first name you wrote the first time)
In my case I wrote a BAD alias. To fix it, I deleted the Configuration and create a new one, with the right alias name. Then it worked.
Tell me if you are able to do it.
