First name error

Hello,

I gave a quiz to CentraleSupélec students this morning using Evalmee. Several students reported errors in their first names on Evalmee: they were logged in with the correct email address, and their last names were correct, but not their first names. It seems to me that external first names have been entered into the system: a student named "Allan" had "Guillermo" on Evalmee, even though there was no "Guillermo" registered for this exam. Similarly, a student named "Thibaud" had "Célian" on Evalmee, even though there was no "Célian" registered for the exam. For my part, everything seems correct in the student grade report, but this bug disrupted several students during the exam.
