Tests are running twice even if only one Test Configuration is set in the Test Plan

Hello,

Did anyone succeed to chose a specific Configuration from the Test Plan to be used for running tests using Test Plans on a Xcode Bot?

I tried multiple possibilities with no success.

We can pass to xcodebuild the following parameter and it will run the desired test plan "test -testPlan NameOfTheTestPlan",
but if there is only one configuration under the test plan , all the tests will run twice because of the default "Share Configurations"

Any ideas?

Thanks!
