Digital Deluxe Edition - Epic Store

Got "Humankind" on free weekend through Epic.
Bought all the DLC - including the Digital Deluxe Upgrade
All DLC, except "Digital Deluxe", are working fine.
"Digital Deluxe" will not register as owned. Even though stating owned on Epic store.

In a previous thread (Thread) there's previous mention of this bug happening before on Xbox game pass.
(Media pertaining to said issue: )
Have looked to see if anything has been said or even addressed, but nothing. Hence, a new post about the same problem from years ago.
