Abstract types form Form editor derives wron enities into xml

Hi!
When defining absrtact types in Form editor causes all entities from the defined concrete type into the xml even thought you have put date into a singe one.
We are using v3.5.1

Look attachment!
Abstract type: LaskennaOhjaustiedot
Dta into: HaetaanKelaTiedot=Ei

The result should be:


                    Ei




But the result is (where even HaetaanKelaTiedot=?, see also odd xml-fragment-element):


 
  ?
 
  ?
 
  ?
 
  ?
 
  ?
 
  ?
 
  ?
 
  ?
 
  ?
 
  ?
 
  ?
  ...

This is working fine in version 3.0.2!
