CA Unemployment request for separation info?

So I just started receiving benefits, and received a request for separation info. It is in regards to a job I had 2 years ago for 2 weeks and they said I quit by abandonment but I actually spoke with my boss there and told him I was quiting. I left for another job in which I quit after 8 months in turn for another job then I got laid off. That is why I am collecting unemployment now. Why would they send a request for separation info. Will I lose my unemployment?
