MC Preprocessor Object Content Generation Issue
In some cases when you used a MC Preprocessor object as a first process step, its content was placed in EXECUTE section of output rule. This issue occurred when you use several separate subprocesses on a worksheet. The code was updated to resolve this issue. MC Preprocessor content now is always generated on the top level of MC stream cascading preprocessing rule when it's used as a first step.
