[RPG] For the ability ‘Expertise’, can you use it more than once on a skill

dnd-5e

Expertise: At 1st level, choose two of your skill proficiencies, or one of your skill proficiencies and your proficiency with thieves’ tools. Your proficiency bonus is doubled for any ability check you make that uses either of the chosen proficiencies. At 6th level, you can choose two more of your proficiencies (in skills or with thieves’ tools) to gain this benefit.

So say I wanted to use my first expertise on Stealth, would I be able to use it again to increase my Stealth once I hit 6th level, or does it have to be on 2/1 different skill(s)?

Best Answer

No. That would not be "two more of your proficiencies". You have to pick different ones.
