Currently the date formats default to MDY format and there is no way to change this. Since most of the world uses DMY format [1] it doesn't make sense to have MDY as a fixed format. It's confusing especially with ambiguous dates (e.g. 10/4/2018 could be 10th April or 4th October).
There should be a localisation option for your user profile that should format the date in the UI either by auto detection or fixed profile-based localisation.
At the very least it should auto-detect based on user locale.
