Achievements All Locked

Hi, 

I have digitally bought minecraft from the Nintendo eshop, once installed I opened a survival game on peaceful and easy settings (never creative mode and never cheats enabled) but the achievements have always been greyed out and everyone says locked.

I have tried making a new game and went straight into the achievements screen and they are still all greyed out. 

 

I have read it may be because its a digital download and not a game card but is there a resolution to this issue?

 

Thanks
