Columns Automatically Unhiding With Form Submission?

Hello all, 

We use a form for our open order sheet. We removed an item from our product list and I want to hide this item in our open order sheet (not deleted it, incase we add a new product because I already have all the automation and reporting set to include these columns). I have NUMEROUS hidden columns in this sheet, but for some reason I have all my columns hidden but then when we use the form to submit a new order to the sheet only these 3 columns are unhidden upon a new row being created.... Why? I have removed the selection from the form and hidden the columns on the sheet - but then it keeps reappearing, what am I missing to keep it hidden?
