I joined my mcpe account 2 years later and everything is reset

I used to play on my android tablet a few years ago and i had about 80 or more achievements and 800 hours playtime. I quit mcpe for few years and i was playing on java edition. Now i bought minecraft for ios and when i logged into the same mcpe account, my achievements, playtime and anything that is in main menu is reset. I went to a server i used to play and everything was there so i think this is a bug
