Simalteneous allowed options question

Hello,



I am testing allowed options on 3.01 and simaltaneous - allowed scenario does not work in the right way.



I have 2 options groups.



First: Small or Large (radio)

Second: If Small chosen => model 1 / 2 / 3 and if Large chosen => model 4 / 5



So I have created 5 varian combinations. And configured allowed options model 1 / 2 / 3 for Small and

model 4 / 5 for Large…

So if I choose sequential / allowed => everything works correct. But if I choose simaltaneous - allowed => Large variant disappers from first options list, so accordingly you can not choose models 4/5.



Is it normal CS behavior or it is a bug?
