Summary:
The Practice functionality behaves inconsistently depending on where it is accessed.

Steps to Reproduce:

1. Login as a Student.
2. Navigate to the Subjects page.
3. Select a subject and click "Practice".
4. Observe that the practice session starts successfully.
5. Navigate to the Student Practice page (or another Practice entry point).
6. Select the same subject and click "Practice".

Actual Result:
The system displays the validation message "At least one topic is required" when starting Practice from the Student Practice page, even though Practice works successfully when accessed from the Subjects page.
