The Story points field appear as Story point estimate in the new issue view.
These are still 2 different fields, the naming just appears differently for sites with the new Story point estimate field enabled.
Also, from JSWCLOUD-17173:
By default and part of the rollout for the Estimation for Next-Gen projects, Jira now has two Story Points field.
- Story Points
- Story points estimate
id customfieldtypekey cfname 10015 com.atlassian.jira.plugin.system.customfieldtypes:float Story point estimate 10021 com.atlassian.jira.plugin.system.customfieldtypes:float Story Points
The default field that is used by Jira classic projects is the field Story Points.
If you, when using the Jira old view, add the Story point estimate (Next-Gen estimation) field and assign the number for the story point, this field does not work and the number is not displayed on the cards or at the new issue view or in the reports.
Edit the issue view screen for the project and remove the un-necessary field.
