When you create a “global instance”, the link number it has means that anything you add with that same link number will use that exact same instance. Not a new copy of that VST/VSTi, but THAT specific setup that you’ve already used.
If you want to use multiple instances, you can, under the device list, right click on the instance you already have (either the folder they are in, or the device itself) and Podium will create a new instance automatically for you, possibly not in the way you’d expect, but try it and see.
