Students See Admin-Completed Modules After Redeeming Course Code

Is there a way to reset a Code Admin Account (e.g. the  email address removed for privacy reasons) used for Microsoft Learn learner course and achievement code generation including distribution?

Preparation completed by a TSP using the Code Admin Account appears to be carried over to students when they claim their codes. As a result, modules that were previously previewed by the admin are already marked as completed in the students’ module lists once their codes are activated.

I may be missing something, but I’ve attached an image showing how students see some course modules already ticked as completed after redeeming their course code.

I also have a related question: are trainers able to view their students’ progress for Microsoft Learn training materials redeemed through these course codes? Specifically, can trainers see whether their students are progressing through the self-paced learning modules?

If these questions have already been answered elsewhere, I would appreciate being pointed in the right direction.

Any input or guidance would be greatly appreciated to resolve any or all of the above. Thanks in advance.
