Hi reyesyaslin68,

Due to the new update and frequent changes to make the LSAT section more flexible, they have redesigned different things in the LSAT section. I too lost my future progress for my LSAT progress and have to re-take the diagnostic. There was also an update concerning this here on Khan Academy help center. 

I can send you a link.

Hope this helps and if you have any other additional questions, feel free to ask.
