I've tried manually switching my final prediction by selecting and clicking on "Save final" button but it doesn't seem to work.
I know I can always resubmit and select final in the form but maybe someone else will have similar problem.
can you send me an email with the name of solution that you want to select as the final?
I will check this and try to solve the problem.
If anyone else is experiencing this issue, please report it asap.
I also had same problem and now select final when submit
