Process stopped

Reactivating this topic. Quick synopsis: I applied to a 3 letter agency in 2018 for a Contract Linguist position, completed BI, poly and favoroubly adjudicated and got a call from them to come for “processing”. Long story short - I never got to the read in step, so never got the TS (you can read the whole story above if you want).
I was told by someone on this board to submit FOIPA request, which I did and have received it a few days ago. I am not a lawyer, but that thing looks useless to me, I dont see anything there that would say that my investigation was successfully completed or anything like that. What am I supposed to do with it?
I am currently being processed by a contractor for a DOD client for TS/SCI clearance. They had to start over because they couldn’t find anything under my name for the investigation completed by that fed agency.
I would still like to persue that agency’s opportunity, just dont know what to do with that FOIPA report.
