Download this from Blackburn. It will give you an idea how it all fits together even if it's not a Blackburn pump.

Not all pumps come ready for schrader. Maybe you have to reverse the head parts.

They should be designed to fit both styles of valve, but you need to reverse the seal.
you should be able to unscrew the end, remove the sealing rubber and a plastic fitting that pushes on the valve, replace them the opposite way around ,and they will fit the presta.

I had the same problem, Blackburn knows about the defect. All you have to do is call their 800 number and if everything goes as it did for me, just tell them your name/address and they say they'll send a replacement head. We'll see if it gets here in the next 7-12 business days.
btw, the new replacement head isn't the same dual one that you and I have, it is a new one with only one insert that can apparently fit both dunlop (car tire) and presta (skinny bike tire).

Ensure the side lever on the valve attachment is turned towards the wheel

When you remove the tires while changing inner tubes, do you run your fingers through the inside of the tires to check for thorns, wire, nails or other debris before replacing the tubes? Also, check to make sure your rim strips are adequately covering the spoke nipple holes in the rim. Sometimes just a little bit of a hole left unprotected can damage a tube. Lastly, sometimes you will just get bad tubes. It happens.

Dear Doug, to lock a hand pump onto the valve stem: 1.depending on valve type-loosen the valve lock for presta, twist off valve cap for schrader. 2.unlock the pumping handle from the pump so that you can actually "pump" the pump... 3. put the pump head on the valve of the tire, then pull up on the thumb tightening lever. This should squeeze toghether the internal rubber gasket of the pump, and lock on to your valve. 4. Begin pumping. 5. when desired pressure has been reached, push down on the thumb lever to unlock the pump. Remove it. Good Luck Fellow bicyclist!
