Why did my Fitness Awards not transfer to my new iPhone?

so i was given a iphone 12 recently and i had previously had a iphone xr and a apple watch series4 , after backing up my iphone xr , i transferred all the data onto the new phone . after a long process of downloading the latest ios and transferring the data i got onto my fitness app to connect my apple watch after syncing it to the backup file everything came through to the correct date other than my awards/ badges and this had upset me as i had completed all the monthly challenges and many other aspects throughout this year and now only have a screenshot on my old phone of this
