These bugs might in some cases prevent you from compiling more elaborate examples.

107 -You can do several transformations on SCCharts (*.sct files). Just right click the file you want to transform in the project explorer and select the Transform SCChart sub menu. As abo is already a Core SCCart you do not need the core transformations. Click the All Normalize Transformations, this will do the Split Trigger and Effects and the Surface and Depth transformations together (in this order).
