The miscellaneous charge should just be for the setup time, so the labour will have setup time, but your costing sheet will also have indirect costs on the cost group associated with the setup category in the work centre. It is difficult to know without seeing the costing sheet and routing etc, but I suggest you setup a new route for the item with one step, assign it a setup cost, no run time or quantity cost, run the calculation and look at the price miscellaneous charge on the pending price, and then on the complete calculation look at the tree structure tab to see how the indirects are calculated. Much easier if you strip it back and build it up. It will also depend on the type of indirect, fixed or variable and how these are applied and at what rate. You just need to strip it back and reconcile it, basically the miscellaneous is only setup and the related indirects, it is not a split of labour - the reason for this is that the labour run time is directly attributeable to the quanitty you make, whilst the setup costs are shared by the quantity, so you should calculate the standard cost based upon your standard batch quantity to get a cost of the miscellaneous and quantity to create variations against, if your calculation always has a quantity of 1 this will skew the standard cost high.
