[QUESTION] Entering S'Orel palace on Morag (-possible bug !?)

[macce2]

When entering the S'Orel palace on Morag, after getting inside the castle
(you could do that freely, although you do have S'Orel key at your inventory);
you see a (door with) calters.
That door Does seem to look like a possible "candidate" for the s'Orel key,
but does seem to open without any key or lockpick (no door lock screen).
You see a monster behind the calters.

Is the case valid or is there a bug ...?!
So maybe my assumption of the place to use the key was wrong...!?

Sorry, please forgive my hastiness;
I was totally wrong with this.
I will close this issue as irrelevant now.
