I have the same issue, although I am on Windows 10. It's the only achievement I have left to unlock, but no matter what I do whether it's crafting the wool, mining it, etc the progress is permanently stuck on 6%. I tried to get the achievement on another account and it encountered the same progress bug.
If you could look into it, it would be appreciated.
Thanks.
