I can’t get the bf1 premium pass for free via ps+ because I own the disc version

I bought the battlefield 1 on disc when it first came out for PlayStation 4.

now a premium pass edition is available in the ps store via ps+ (my friends downloaded it without any problems)

But I can only download the regular version even after deleting the game from my PlayStation.

and the dlc’s and premium pass is only available for purchase.

So can I just not get the premium pass without paying full price? Or is there anything to do?
