I need to move  Weight (weight) and Cost (standard_price). I did not encounter an error when setting it as "invisible" or replacing it's position (position="replace), and calling it again to a different view. However, what i am encountering is that the field is still visible to its original state.

For example:

Weight field in Product can be found in Inventory tab.

What i did is:

Upon refreshing the view. "Weight" is still showing in the Inventory tab, as well as the General tab. This also apples to "Cost" (standard_price)
