Не могу разобраться с `FSMContext`, `State` в `aiogram v3.x`. Пишу систему регистрации

В результате моих "непониманий" функция show_summary в приведенном ниже коде выводит значения некорректно. Вот что выводится по итогу в (show_summary):

The following is a summary of the information you provided:
Student Name: (Parent) # Здесь по какой-то причине выводится/принимается первое значение (`Parent`) из первой в коде функции `command_start`, вместо `student_name`, следовательно, нарушается и остальная "последовательность".
Date of birth: (full name)
Parent's name: (YYYYY-MM-DD)
Parent's phone number: (full name of (parent))
Thank you for enrolling your child. You will receive further instructions.

То, что в скобках, я ввел вручную во время тестирования в Telegram боте (для демонстрации)

Сообщение/show_summary должно быть по идеи такое:

Here is the summary of the information you provided:
Student Name: (Student Name) # И так оно и должно быть по идеи.
Date of Birth: (Date of Birth)
Parent Name: (Parent Name)
Parent Phone: (Parent Phone)
Thank you for enrolling your child. You will receive further instructions.

Вот полный код:
