Hi,
I have some system fields duplications.
for example : target end field (it's system field which is LOCKED).

I assume someone created custom field with the the same name "Target end"
Now I would like to separate them as it makes confusions everywhere across Jira.
in custom fields I see this system LOCKED field but I cannot change context or even see a clue for the addition field with the same name

Any idea how to change the custom field name that is hiding behind the system field?
Thanks
Gal
