Issue Summary

Team managed project fields are displayed in Scheduling configuration of Plans even when the issue source doesn't include issues from team-managed projects. The simple fact of existing a date field in a team-managed project, it populates the dropdown for Start Date and End Date of the plan scheduling configuration.

Steps to Reproduce

1. Create a plan
2. Set its issue source to company managed projects
3. Create a team managed project
4. Add a new date field to the team managed project
5. Access the plan
6. Head to the plan scheduling configuration
7. Expand the dropdown for the Start or End date to see the field with an ID next to it, which indicates it's a team managed project field.

Expected Results

Plan shouldn't display team managed project fields as it doesn't support team-managed projects.

Actual Results

Plan displays team-managed projects greyed out as they can't be used, indicating an error message as "Make sure to add this field to all the issues sources of this plan".

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
