Logic Pro 9 EXS24 sampler instruments saving, confusing

#1
I'm a bit confused with the way saving/loading of sampler instruments is designed. I've noticed the controls in the GUI doesn't always get saved and there's a difference between saving in the plugin GUI directly or saving from the Sampler Instrument editor. Is there a brie explanation on how these things are related?

I tried to figure it out by trail and error but I didn't get the full picture.
