Moving issues in issue board from any list to the "Open" list doesn't work.

Summary

I have an issue board called "In Progress", and I want to move an issue from it to the "Open" list. When I do it and refresh, the issue is back in "In Progress".

Steps to reproduce

• Create a list in an issue board.
• create an issue.
• Put it in the new list and refresh. See that it's still there.
• Move it back to the open list and refresh. It will not work.

What is the expected correct behavior?

• After refreshing it should be in the list I dragged it to.
