Achievements do not work in realm with the included experimental gameplay (ex)!

I play my realm with friends, my nickname is BlusterySasha (XBOX), I play Minecraft Windows 10 Edition. Experimental gameplay is included in my Realm and probably because of this, achievements do not work! I spent a lot of time on some of them, I observe that many have such a problem, they all spend a lot of time to achieve, and they do not work!
