I developed a flows with 2 screens, first screen request a data_exchange to server and receive all data on second screen in right way first time, but, when the use click on back button to go back to first screen and input a new data and request data_exchange again, the second screen keep the old data on inputs, but you can see on screen that the input description the value is the right value received by data.

resume: the data that you receive after a back screen keep old on screen but the variable $data is with right value.

Someone with that problem?

To reproduce this issue, you can create 2 screens, first screen is a data_exchange, you go to second screen, click on back button for first screen, request a new data and continue the flow, you will see that the form on second screen with the initial-values received from data will be with wrong value, is going to be the result from first request.
