Maarten, the cut list is not converting the solid bodies to any other format but just organizing them into folders with additional properties.
Are you getting any issues with cut list being there in the model?
Right click on the Cut List(11) folder and turn off automatic update. Right click again and select delete. Now only the solid bodies will display. When a model has sheet metal features in it, SW automatically renames the Solid Bodies to Cut List (you may be able to rename it back to solid bodies but I'm not at my computer right now to try it).
My problem is solved, thank you both.
