Inconsistent documentation for edit student

[nus-pe-bot]

it is mentioned that student number cannot be edited here

However, on the UG, student number is one of the fields that can be edited according to the example shown below

Users might be confused why they could not use the sample command successfully should they refer to the table at the end of the UG

Team's Response

Changed to severity very low, Command Summary was meant to be looked at as a quick reference for the user after they looked through each individual feature.

Duplicate status (if any):
