Cutting wizard greyed out, why?

1
When I try to set the span (envergure) and gaps (decalage)in the cutting wizard I find these numbers are grayed and not able to be edited.

I can find nowhere else that they can be edited either.

How do you cut wings that are longer or shorter than the (apparent) default of 600mm and what if your table is wider than the 620mm which seems to be the hard-coded value (span + 10mm at each end)?

What am I missing here?

It's okay, I found that the wizard box had to be checked elsewhere before the wizard values could be altered.

Is it just me or do others find it rather hard to find their way around this software?

Does anyone want me to write a tutorial (in English) to help other "newbies"?
