Transformer Figure 8 error.

Can you tell me what was changed on the schematic on Figure 4?
Comments
AN-46 says,"Note that when using an integrated transformer (large built in
leakage inductance), transformer leakage inductance (LSER)
changes when primary turns are changed".
If if I start a new design in PIXIs Designer HiPer and change primary turns I see no effect on Lser.
Is this to be expected?
PIXIs designer cell 134 says,"Estimated L_AID based on Lser, Lopen, Npri and Nsec. It strongly determines effective turns ratio and operating frequency. For better accuracy enter measured inductance of primary and ONE phase of Main secondary connected in 'series aiding' (see AN-41)".
I can't find any reference in AN-41 to L_AID.
Can you point it out to me?
The location of the designator for the 30 volt zener VR6 was moved to make easier to read.
