Hi Team,
I've updated a custom field in our test environment and can clearly see that this update has been saved. However - when I review the screens that this field is assigned too, it still shows the old custom field name (also when I create / edit issues, the old field details are visible).
I've completed a reindex and also given it an additional 24 hours. 

What am I missing? Can you not update custom names fields in JIRA?
Thanks,
Steve
