Personally, I don't see the difference.There should be an achievement category.... as well as milestone category. Differentiating between the two would be good to me.
The way I use those words all Achievements are Milestones and isn't reaching a Milestone an Achievement?
You seem to be of the opinion that an Achievement outranks a Milestone and is more important, but my quick google results for
"What is the difference between a Milestone and an Achievement?
returns this:
This seems to be the opposite of what you are saying...A milestone represents a (very significant) step along the way; an accomplishment is a triumph in and of itself, even when it is also a milestone on the way to something else… They are sometimes used as synonyms, however a milestone is a great accomplishment. A milestone is more significant than an accomplishment. english.stackexchange.com
Regardless, for decades video games have been using the term Achievements in this way and I don't feel the need to change that.
