Some instances of TestRuns[n].Executed By ended up blank

I am using Xray and Xporter in their latest versions. I ran a Test Execution were two of the test runs were executed using normal logins and two were executed using temporary logins. When I reported on the Test Runs using Xporter, ${TestRuns[n].Executed By} is empty for the two temporary logins.

Steps to reproduce:
1. Create two users (userA and userB)
2. Create Xray project with one Test Execution, and add some tests (Define test steps)
3. Execute test with userA.
4. Export with template:
Xray Test Execution Results Report_.docx

5.Validate the fields "Executed by" are filled:

6. Logout
7. Login with userB
8. On TE execute one test
9. logout
10. Login with admin user
11 . Delete userB
12. Go to TE and export usingt the same template
13. Validate fields are empty:
