"Summon Tane" button misbehavior

When I'm in a special sub-area like hideout unlock zone (where you enter and kill monsters to unlock a new hideout) or atlas citadel, big metamorph button is greyed out and says I'm too close to the vial. It should say something like "cannot create metamorph here".

After I create and kill a metamorph, the button is still green, but clicking it does nothing. It should either disappear or be unclickable with a message like "you've already created a metamorph in this zone".
