Yes, that's correct and it's intentional. To also set the sliders you
need to send a "set" message to every [originator].  This is easy to
do if you use the "hidden" receive target: "SET_ALL_RRADICALS", that
is mentioned in the help patch for originator. 

What is happening here is the following: loading a state from disk or
from memory is considered a different operation than actually
activating this or another state and because of this they are handled
by two different messages to [originator]: "substate NUMBER" loads a
substate NUMBER and "set" activates the currently loaded substate.
Both can be done in one step as well by using the combined message
"setsub NUMBER"

Now what you load through the "careGUI" actually is a collection of
many such substates. "careGUI" cannot know which one to activate, so
activation is in your responsibility and you should use a "substate
NUM", set" or "setsub NUM" message. You can use the outlet of
[careGUI] to start this activation: It will receive a "bang" after a
new file was loaded.
