Rekall fails assigning story points but the JIRA story points field is properly set

It may happen that Rekall fails to assign story points and mention to validate the story points field in the admin section. However, the admin section shows that the proper field is assigned. If that is the case, select another value, re-select the proper value, save the changes and then try again. It is possible that the value was not properly detected and saved during the initial installation of Rekall.
