The achievements seem to be sorting by most recently earned at the top and oldest at the bottom. I get a sense that this is how it always has been but if it is possible I think for the dungeons, it should be sorted like this:
1 - All normal
2 - All veteran
3 - Hard Mode
4 - Speed Run
5 - No Death
6 - Challenger
7 - Trifecta
Other than that, I do like that this is consistent with the armor collection!
