Signing in on new computer reset my progress

I just got a new laptop. I tried signing in and it is showing I have half of the projects I have done and half of the exercises are checked. On my desktop, I have 6 projects, 1 certificate, and 461 coding challenges done. On my laptop, it is showing 255 coding challenges, 3 projects, and 0 certificates. I know 100% sure I am signed into the same account…
