Our goal was to have a dog on each ear
I prefer my two-headed race monkey catch dogs to catch on either end and not both ears. That way the monkey makes a huge squelching sound when the two headed dog pulls it apart. In fact, in the two headed race monkey catch dog standard it specifically states the two must catch on either end of the monkey, one on the nugget the other on the rump. I am afraid your dogs are culls. I'll still take one though.
Your statment is proof there will never be aperfect catch dog! I raised a bulldog with two heads and you culled it!
