Hi, thanks for contacting me.
Regarding your first question,this is a bug, these field names should load.
A workaround would be to simply uncheck that checkbox and manually make sure to specify the placeholders in the correct order. For our part, we will look into this problem
Regarding your second question, I understand that you would like that once an order is no longer in pending status, it can be removed from the sheet?
If so, it is not possible at this time. Sheet update is not supported. Perhaps in the future there will be such a solution.
As for the values given by the customer, the placeholder : order.meta can be used for this purpose, but this data must be written in the meta of the order.
In case they are somewhere else, then the easiest way would be to write your own placeholder to pull this data.
Greetings,
