pattrstorage bug?

I'm working on a system with 8 bpatchers, every bpatcher with his own autopattern object.

Every autopattern object has his own name, but when I open the pattstorage called f.e. "bpatchPreset1" from the main patch, all the data of the system is reflected and not as expected the data from the first bpatch.

Is this a bug or may I'm missing something.

Thanks!

add: no matter how I call the pattrstorage object, the object always reflect all the system data.
