I am hoping this question has a really simple answer to it.
I am currently in SharePoint Designer editing an
I added an empty data view, then added a data source for one of my document libraries. I can then select from the ribbon the columns I want add from this library, it then puts all the code into designer. Then when I click save to preview it in the browser, the code in designer changes from the one initially put in. The option to add and remove columns for that library is then gone and I can no longer amend the information from that instances.
Why does the code change when you save it and why can I not amend that data view once I have saved it?
I am using SP2013
