Are you making sure that the numbers inside of each material section say "2"? In my example below, note the top line. Each part of your preset, that first line (bodyMatL, bodyMatR, headMatL, headMatR etc) should have a 2 listed next to it.
material preset_2_bodyMatL
{
technique
{
pass
{
texture_unit
{
texture preset_2body.jpg
}
}
}
}
