Hello,
I checked your purchase and it is Platinum Edition purchased on April 2019. This edition includes only Living Weapons not other DLCs.
Platinum Edition: Digital product key for Phoenix Point, includes Alien Living Weapons and Armour DLC, digital art book, ebook and soundtrack, and Early Access.
If you want Blood and Titanium and Legacy of the Ancients DLCs from the Epic Store there is this: Phoenix Point: Year One Edition - Upgrade - Epic Games Store.
