It's not possible to export defects when there are tests and test sets in links

It's not possible to export defects when there are tests and test sets in links.

You can't export defect count when you have an iteration for links test sets and tests.

Test steps to reproduce:

1. Have a story with links "is tested by" to a test set and a test
2. In both (test set and test) add defects in execution page
3. Upload this template  cloud.docx and try to export
4. Error: the defects count from the test don't export

But if export this template  test (1) (1).docxthe defects count are exported
