Changing start and end times for hourly activity goal

[Survivor2]

I would like to change the start and end times for the hourly activity goal but when I enter the new times only the "cancel" button is highlighted.  The "OK" button stays grayed out.  Is there another way to change the times or am I doing something wrong?  TIA for any help!

On the computer or Phone would help?

But on the computer you are not seeing the Save button?

Thanks for your reply. This is on both my phone and tablet. In the pop-up box where you change the times there is no "save" button, only "cancel" and "OK".

How to change activity start and finish times on my Fitbit Alta as it shows 7 hours activity and keeps defaulting to times to confirm this if I alter start isputs in finish time and if Alter finish time it alters start
