I have tamed 5 wolves in Minecraft Survival, yet the achievement isn't unlocking for some reason. As a result, I am unable to get the Wolf Mask reward as well. As you can see in the first screenshot, the achievement says I have some progress remaining to unlock it. However, in the second screenshot, you can see it says my progress is 5/5 or 100%, so it's almost certain I have completed the requirements for the achievement, yet it won't unlock still.
