software error

with the following requirements
12V 1 Amp, 5V 50 mA, 18V 50 mA with universal input supply.
PI Expert shows with ee19 core, for 12 V winding 4 turns, 18V 3 turns and 5V also 3 turns with primary of 55 turns, I think 18V truns should be more than 12V turns may be approx 6 T, but 3 turns for this winding seems like an error in the software.
Please clarify
The software assumes by default that you want to use AC stacking which means that the 18 V winding shares all the 12 V windings turns in addition to the 3 turns shown.
So the 12 V winding actually has 7 turns, 5 V winding has 3 turns and the 18 V winding has 10 turns.
