Bug with NSForms expanding to more Cells

[buzzdeee]

I tried to use a NSForm.
In Gorm I drag 'n drop the NSForm onto my window.

Then in its Attributes, I set the number of fields: 4
The NSForm expands to 4 NSFormCells. When I set the connections between the cells and my outlets,
I see the first 2 called: field1 (FormCell(0)) and field2 (FormCell(1)), but for the 3rd and 4th cell I see: field3 ((null)) and field4((null))

example code can be found here: https://github.com/buzzdeee/Test2

I'm using gorm-1.3.1, with otherwise latest gnustep make, base, gui, back releases.
Can't easily update Gorm, due to: #35
