Can't change store kit renewal rate, stuck at every two seconds

I wrote a StoreKit unit test and set the renewal rate to .oneRenewalEveryTwoSeconds for the test session. But now my App expires and renews every two seconds when running normally, even though the StoreKit Configuration file is set to "Real Time." Changing it to anything else doesn't change the renewal rate. I've tried cleaning the build folder.

If, however, I set my SKTestSession explicitly to .realTime and run the test again, then my app behaves. However, again, it doesn't matter what I set the Configuration Settings to.

Anyone know where this information is stored?
