Getting Unresolved References error (IES01011)

Hello,

Using the IDT 4.1 support pack 5

I have a callculated object that clalculate from 2 other objects.

Object  = @Select(Obj1) - @Select(Obj2)

Im getting this error.

if i put the DB calculation instead of @select function it works fine.

if i put only one @select function it works fine.

I'm getting it only by putting 2 @select functions.

in other objects it work fine.
