The issue filed "Remaining Estimate", which according to this link appears to be standard, has totally disappeared from my Jira Core.
I try to find it in Settings -> Issues -> Field Configurations -> Default screen configuration (which in theory is where I should see all standard fields), it just is not there. As if it never existed. But, I also use BigPicture and from there there's a view which shows me all the standard fields of Jira Core issues, and "Remaining Estimate" is right in the list.
How can I do to make it come back?
Thank you very much in advance
