When trying to add a new row, it takes me to a random row that is already on the data

When I click on "add request url value" It takes me to a random row that it in that data already. But I want it to take me to a new and clear row. 

 addRowlink: a!dynamicLink(
            label: "Add Request URL Value",
            value: {
              CRETD_BY_USER_ID: loggedInUser(),
              CRETD_TMST: now(),
            },
