Jake says "Alors vous avez pris le problème into your propres mains?"What does propres mean in this sentence?

In French, “propres” means “own” in the phrase “prendre le problème en vos propres mains,” meaning “to take the problem into your own hands.” It agrees with “mains” (hands), which is plural and feminine. “Clean” can also be a meaning of “propres” in other contexts, but it does not fit this expression.
