Can't buy The Surge Augmented Edition

I can't find a way to speak to/ message someone that works for Sony so I figured here is my best shot.

I got the Surge on PS Plus a while back, then thought about buying the dlc. I went to buy the Augmented Edition which includes all dlc for €12,79 or thereabouts on the store. However when I go to the store page it says that it is unavailable as I already own two dlcs; things I don't remember buying or that were automatically included in the PS Plus version. This means that because I can't buy the Augmented Edition I have to get the 3 paid dlcs separately which leaves me worse off, is there a way around this?
