custom fields with the same name used in the different Team-managed projects cannot be exported correctly

Issue Summary

When there are custom fields with the same name used in the different Team-managed projects then you cannot export them from the issue navigator to an Excel sheet. They will appear blank in the sheet.

Steps to Reproduce

1. Create one or custom fields in different team-managed projects with the same name
2. Fill value for these custom fields in a couple of issues of the different team-managed projects
3. Now search for these issues in the Issue Navigator
4. You will be able to see the values for custom fields, now click on the Export to Excel (CSV) button to export it
5. You would see that value would not appear for all the fields in the excel sheet. Check the video attached below. 

Expected Results

As the values are shown in Issue Navigator, hence they should be visible in the export as well. Check video replication here: export of custom field from Team Managed project.mov

Actual Results

Values are not exported in excel sheet for these custom fields

Workaround

Create the custom fields with different names in the team-managed projects
