Steps:
1. Login to JIRA. I am using customer data https://support.atlassian.com/browse/JSP-35690
2. Login as arrowsmithn and I added "assigned to me"
3. In configuration user has selected 10-15 columns.

Result:
1. JIRA is unable to handle the scenario.Please see the attached snapshot.

Expected:
1. The handling should be better here. Till 3.13.5 we don't give user option to select their columns but in JIRA 4.0 user can customize it but the scenario like these should be handle better.
