Why does a compiled network start embedding audio file references when it was set to use an external slot?

I have a network with a SNEX node that plays a sample. It is setup to use External Slot 1. But when I compile the network, it starts embedding file references instead - ie; I was expecting embedded data in the XML to be empty or non-existent.

@Orvillain did you clear it out before setting it to the external slot?

No experience with snex audio files but if you create a table, draw a curve or something, then switch to an external slot, you can switch back and forth between the embedded response and the external slots, meaning the embedded data is always kept.
