Personalize Sourcing Negotiation

I try to personalize a table from  sourcing negotiation, the table of "requirements", column of  "weight", but when I put the option Rendered in false,the column did not disappears, any other column of the table that I try to disappears with the option  Rendered in false it works correctly but the column of Weight did not, is there any reason or is a native funcion that not lets to hide  the column ?

I am working on version 12.2.4.

Thanks
