Export a g8 female model with heels using FBX

stagefeet

Hello to the great DAZ comunity.

Im pretty new to DAZ (4.10) and cant find a solution for my problem:

I have a g8 female model and she wears high heels.

So, the model stands on her tip toes.

When i export the model in .fbx format

all is fine except the ankles of the foot (tip toe position) are not exported right.

The exported model stands flat.

I tried several hints from the web (Edit->Figure->Bake To Transforms), but no succsess.

What do i need to change before i export?

Attached are my export-settings.

Thanks for reading.
