magento2 – Ignore column table does not work in data migration tool

I'm adding a custom column to my Magento 2 quote column which is shipping_delivery_date

I have a warning error when I migrate the data:

[2020-02-27 02:37:24][WARNING]: Destination fields are not mapped. Document: quote. Fields: shipping_delivery_date

i tried to ignore this column:

  
    ........   
    
        .......
        
            quote.shipping_delivery_date
        
    
  

but i still get the same warning
