This here was taken from the 1.20 Patch Notes:

≪Future Expansion of the Achievement System≫

Status of achievements in progress
1. The display of current progress for achievements (such as percentages and kill counts) will not be available in patch 1.20. We will be adding this feature sometime after 1.20a
2. As of version 1.20, it is not possible to verify locations you have traveled to as part of various exploration achievements. This issue will also be addressed after patch 1.20a.
3. Additional Achievements
New achievements will continue to be added following release of 1.20a.
