What does Pre-Lit 10 and Pre-Lit 40 mean?

r/

It’s not legal advice it’s more of a question because my family is currently going through a legal process right now and that’s what our case was updated to. It was Pre-Lit 10 a month ago and now it’s Pre-Lit 40. It may not mean anything at all but we were curious and couldn’t find anything other than it’s days?
We are pursuing a lawsuit if that helps with it. We submitted more documents last week and that’s when the update status changed. We are hoping it’s good news. Thank you for any that help with this question.
