Replace function not working

Hi,

I have a problem with the replace function.

I created a text box in a view of my product by assigning the "Replace" value  to "col1".

In another view, I created another text box in which I also assigned the "Replace" value to "col1".

In single parameters of products, I set the "Replace an all view" option to "Yes".

Yet when I make a change to the view in my product page, the change is not reflected on the other view.

Did I miss a step?
