First name too long for Prometric?

Dollar Store Harvey Specter

Slight problem - I have a slightly long first name, and Prometric only took in the first 15 letters (including spaces) of it. Thus, my LSAT registration only has the first 15 letters of my first name and does not exactly match my ID. Has this happened to anyone before/any suggestions on who to reach out to?

To address any potential questions: I can definitely rule out my own human error, as my first name is correctly and fully entered on my LSAC profile. I also tried to add my full first name on the registration page, but unfortunately Prometric's website pulls it from LSAC and puts it in an uneditable field.

Any views appreciated - thanks!
