Problem patterning slots

OK, I always seem to have problems with slots, but this is a new one.  I created one slot on the left plate, then used the linear pattern function to create the other five slots on the same plate.  I try to pattern the six slots and get this error message.  I can't decrease the number of instances smaller than 2, and since when is 17' too far?  Any ideas?

And while I'm on the subject, am I the only one who would like to have a Hole Wizard function for slots?
