Lost Blitz card progress

I havent Played halo wars 2 in about a year just returned to the game and i lost all my progress from campaign to blitz cards rank all just reset, is there a way to get them back, i dont mind story that much but lost all my blitz cards and the rank

Was it for all of your cards, or just DLC cards?

didnt have dlc last time i played was march 7 2017 and just logged on sept 2018 so i assume alot happened, when i logged on i had 35 packs not opened a few for each hero, but i noticed becase my favorite hero shipmaster at the time i had missing cards and not leveled cards
