There are a few things to check. First, there are two interfaces to translate Altium Designer to HyperLynx SI. There is the old translator that writes a .HYP file from Altium, and there is the newer ODB++ export from Altium. Depending on which method you use, the design data that gets translated might be a bit different. Look carefully and the shapes in HyperLynx SI to see if they are correct.
Next, make sure you have defined all the power nets in menu Setup > Power Supplies. The shapes should be part of power nets, not signal nets.
Lastly, make sure you have enabled the coupling to area fills. Use menu Setup > Coupling Settings and check the box for Include trace to area fill coupling.
Increase D value and decrease G value to get more detail in the coupling to area fills.
Notice that this activates the icon in the Setup menu.
I hope this covers the details that you need to get this to work.
