Hey
@livrobertson,
I would not worry especially because you emailed them and they are aware of the situation, and you also included the original text so I would say you did everything you could have done. It probably was an issue caused by the website. I am pretty sure that law firms are very understanding with things like this.
Last year when I was applying I faced some issues with some application forms and I have always reached out the firm in question for clarification or to update them on some issue I had filling out the form with the correct information and they were all super supportive and understanding of the situation.
Do not worry too much and good luck with the application!!
