Achievements arent Unlocking

Greetings,

Me and my friend opened realms server, we are playing survival and he is progressing on achievements. However whatever i do i cannot unlock the same achievements. Even simple ones such as 'Diamonds to you!' one. I tried everything, opened single survival server but my achievements are locked at 30 and never progressing.

I send bug report earlier, but sadly it doesn't even helped because they think i switched to creative. I didn't! It doesn't work in any server sadly. Even in single player...

Things i tried:

-I tried over and over again for gaining achievements
-Uninstalled and re-installed
-Played on survival (never played creative mode in my life)
-Log out and log in X-box and windows accounts.

Sadly none of them are worked. Please help me, I want to complete my achievements soon as possible. Thank you.
