Running out of Potions

You can see this Rogue has three slots in her action bar reserved for potions. The yellow Ogre Strength Elixirs she has three of but the two health potions she has none indicated by the dull images. You can see in her bags she has none. However, should she pick one of these up and put it in her bag it will automatically be put in the appropriate action bar, saving her the trouble of having to keep shifting potions dwon into the bar.
