Cant find my soase product keys

I don't know what happened to them but my Sins of a Solar Empire  product keys on my account are gone  and the finder cant find them I got the entire Soase collection on steam sins and all its DLC as proof and owned the physical copy of the original? I do not know why my keys are gone for the backups on this website. any ideas where it all went? oh also missing ashes of the singularity.
