I am thinking this page as playlist rename page. So when we go into that page, the values will be filled with the values of the selected playlist. After clicking on update, it will update the changed values while the untouched ones will remain the same.

However, with the current state, when I click on Update without modifying these values, the request is sent as "undefined" for each value. I need to at least click and modify them (add a space then remove, for example) to take values into account.
