Field Items Columns reshuffle after every load

Need Help with something in ERPNext.
I am working in the quotation doctype and there I have a table named Items which contains the columns, that you all can see in the image here.
I want that all this column should be fixed for every quotation I create or for every user in my company that use it to create the quotation.
The issue is for every user the columns are shuffled. I am attacking the image as well
