The leaks were in the same place on both bags; located on the lower part of the sealing valve. I then dried the bags and covered the leaking spots with HVAC aluminum tape. I retested the bags by stuffing them with dry wadded-up paper towels and then drawing a vacuum. The bag with the tighter original seal is working.
