I could not change the final selection in IE. It looks like switching to Chrome helped.
Thanks for letting us know about the issue!
I'm glad that you find a way around it, but we will look into this anyway.
Since yesterday after I merged my members, I found that I cannot change my final submissions. Though I cancel all selected submissions, in the page it continues showing the submissions should limit to max 2 warning. I have tried chrome, IE and FireFox. Besides, refreshing the page and logout my account and login again are not working too.
Thanks for letting us know about the issue. It was resolved and you can set the final solutions now.
