Custom Field disappeared from my Create screen

Rick Brooks

We noticed today that a couple of custom fields disappeared from the Create screen.  After researching we saw that they had no context.  So we added a context to add them to all screens globally.  Now the fields appear, but one - a single select picklist - has no values in the list and all of the existing history is gone also.  Any ideas as to what happened and how to recover?

I had to have Atlassian Support add the default context back to the custom field, then I re-typed all of the options, and used the CSV import to put the values back into the historical issues.  Still not sure why the default context disappeared or why it looks like someone tried to add a new custom field with the same name as an existing custom field.
