The Asset Group ID is not imported when doing a Fixed Assets General Integration.
This is actually the normal behavior of this window. This field is used to default general ledger accounts into the assets record only. Once you have saved an asset with an Account Group ID specified, the associated accounts will be saved against this asset, but the Account Group ID you selected will not be saved on the card.
You can check that the correct accounts have defaulted to the asset by navigating to Cards | Fixed Assets | Account, and selecting your asset.
