Hi,
we have upgraded jira5.0.7 to jira 6.1.7 and jira-misc plugin from 1.5.0 to 1.5.7. By mistake under field configuration i have removed the description formula start tag (<!--) for the custom-field "Risk Exposure"and i have updated. But after that i am not able to see the Edit,Hide,Required,Screens button in jira for that custom field.I have tried setting the description as empty using the below query
UPDATE fieldlayoutitem SET description = '' WHERE fieldlayout = '10260' AND fieldidentifier = 'customfield_12161';
but still i am not able to see those options.PFB Screen Shot, the options not visible for Risk Exposure

Could you please help me resolve this issue.
Thanks,
Jayasingh
