Premium time disappeared even though i had more of it remaining

I recently logged into my war thunder account through my gaijin account on PC , prior to this i used to play on Playstation , at first my premium account transferred over to my PC aswell , but a couple days ago it disappeared out of nowhere , i would apreciate some help.

Premium time from Packs you got via Packs does not Transfer over when you login via PC,
Only Premium time you got for GE/Chests appears on PC

that would make sense but i had premium time from both a pack and bought with GE , only thing i can think of is the 15 days gotten throught a pack are used last? which would make sense because i was
on 15 days left on my console.
