Triggerring the Output Type makes Freight Charges Zero

Dear Experts,

When an Invoice is first made (F2) the Freight charges are determined correctly as the Condition base Calculation Value is correct.

Now When I am trying to Trigger a Output for this Invoice somehow the Condition base value is for the above output type is converting to "Zero" and due to this the Condition value for Freight changes to "Zero".

Now I am not sue how the Output is linked with the Pricing Condition value. I am surely missing something here. Can someone please help on this.

Thanks
