Original Estimate and Remaining Estimate fields not visible in Issue View
Platform Notice: Cloud - This article applies to Atlassian products on the cloud platform.
Summary
If the users are having trouble with standard fields 'Original Estimate' and 'Remaining Estimate' not showing up in the issue view even after adding them in the field layouts, this document will explain the functionality of these fields in detail along with the solution.
Environment
Jira Cloud.
Diagnosis
In JIRA Cloud, the Original Estimate and Remaining Estimate fields are associated with the Time Tracking field. To see the Original Estimate field on the view screen, you need to add the Time Tracking field to the screen. Along with this, the most important fact is that the Time Tracking field must not be set as Hidden in the Field Configuration.
As for the Remaining Estimate, it won't appear as a separate field. Instead, it will be displayed when you hover your cursor over the Time Tracking field. The Remaining Estimate is included within the Time Tracking field. There isn't a separate field for Remaining Estimate in JIRA Cloud, like there is for Original Estimate, that users can configure. I've attached a screenshot below to illustrate this:
We see a 'Remaining Estimate' field in the issue layout configuration section upon searching for it on the left-hand side. This is because all JIRA core fields, including those used internally by JIRA, are displayed here. However, please note that selecting core fields will not necessarily make them appear on the issue view screen.
Solution
In order to allow your team to enter an original estimate when creating or editing an issue, you'll need to unhide the Time Tracking field in the Field configuration by navigating to Field Configuration for the respective issue type and clicking on the Show button and adding the Time Tracking field to relevant screens associated with those operations. See Associating a screen with an issue operation for more details.
I hope this document clears up any confusion. For additional information on Time Tracking configuration, I would recommend reading this support document: Configure time tracking
