Node Wizard breaks the conditional fields settings

Hello,
Node Wizard is a really nice module, exactly what I was looking for.
I've changed some pieces of hardcoded codes for the buttons (proceed to. etc) and everything could be perfect now...

But I've a major issue : I use conditional fields in my content form to hide or display other fields (in the same fieldset) depending on the chosen value.
With the node wizard module, these settings are not respected. The wizard displays every fields of the fieldset...

Do you know how I could fix this ?

Thanks again :-)
