Hi. I copied Cure Light Wounds from a potion and cast it. Then I copied Cure Minor Wounds from a potion and cast it. Then I copied Cure Light Wounds from a potion and cast it. Not a game breaker, but, you know. Is that supposed to happen?
It's impossible to steal the same spell from the same or different spellcasters without first resting if I remember correctly! But stealing the same spell sequentially from potions isn't currently limited.
