When creating your MV Testing campaign, you need to enter an ID. However, if the MV Test "Test 2" ID is the same as the MV Test "Test 1" that was used previously, the data from "Test 2" will not be returned.
As our processing chain keeps the first label encountered for this ID, it will be "Test 1" which will show, regardless of the value of the label entered. You must therefore change the ID associated with "Test 2" to see the data show on your interface.
