A question about celerity

Happy Christmas, everyone.

One of my players is making a banu haqim sheet. We live in Brazil, and here we don't have the player's book translated yet, so he looked for some disciplines on the paradox wiki, which I usually allot, but he had a question that I couldn't answer.

Fleetness

Add a Celerity rating for the non-combat Dexterity test or defending (This may be used once per turn when defending with associated pools).

Weaving

Removes the penalty from dodging multiple ranged opponents (The user can all add their Celerity rating to ranged dodging attempts).

weaving, I add celerity

fleetness I can add one time to a defense

If I have bonuses from two sources,

Do I win both?

like, normally, I would have 10 dice to defend myself

With fleetness, could I choose an attack to have 13 dice?

or can you only add one bonus?

So, what should we do? Is my question clear?
