Not sure if it's me ... but when I first ever selected Celeste, her Dash had a mod that was 2 mod points and was "reduce dash cooldown by 1 if it hits no targets".

The mod once un-selected does not appear in the list of mods ... I can't seem to find it to re-select it ... not that it was actually in the list at the beginning it was just auto-selected (so when you hover over the ability you can see it).
