AI Question - Straw Plugs Failing

I have some straws that don't seem to be sealed properly. They don't dramatically "explode" in the water bath, but the cotton plug seems to allow water in (lots of dead sperm, but still 1% to 3% motility). When I go to actually perform the AI and start pushing the plunger, then the part of the gun that goes into the straw just kinda squeezes past/into the cotton plug... I initially thought that I had loaded the straw backwards, but I tried another with the same result.

Is there a way to "re-plug" frozen straws?

I have the little syringes and connectors to pull the contents out of the straw... but then what?
