Issue Summary

The fields menu in company-managed (formerly classic) projects (plugins/servlet/project-config/{projectid}/fields) displays all fields in the Default Field Configuration including team-managed (formerly next-gen) fields. This can cause inconsistencies in the display of fields on the various screens and may cause confusion to the users.

This is happening for Jira Core, Software, and JSM projects.

Steps to Reproduce

1. Create a custom field in a team-managed (formerly next-gen) project.
2.  Navigate to a company-managed (formerly classic) project which uses the default field configuration
3. Navigate to project settings → fields
4. Inspect the list of fields in the default field configuration. The team-managed (formerly next-gen) field will be listed over here.

Expected Results

The team-managed (formerly next-gen) fields should not show up under the Fields configuration of company-managed (formerly classic) projects.

Actual Results

The team-managed (formerly next-gen) fields show up under the Fields configuration of company-managed (formerly classic) projects which is using Default Field Configuration.
