Stepper moving in only one direction

Stepper moving in only one direction was created by tduckman
I have my stepper wired up correctly(I think/hope/maybe not) When using stepconf or after loading up the example and doing individual steps I can turn my stepper clockwise clicking the + 10 times yields the following results:
1,2,3,4,no step,6,7,8,9,no step
When I click the - 10 times I get the following movement:
right,left,right,left,so step,right,left,right,left,no step
I have a bi-polar stepper wired up as a unipolar.
Only testing one axis now as I assume the other two would act the same.
Thank you

you have an incorrect phase somewhere , or one phase reversed
without the wiring diagram it's difficult to pin point further ,
if you can give information as to your stepper motor and stepper driver and wiring we can advise further

I can't quite explain the no-step (though that could be due to inaccurate microstepping) but the rest of it sounds very much like step and enable pins are swapped.1,2,3,4,no step,6,7,8,9,no step
right,left,right,left,so step,right,left,right,left,no step
