Achievements not being triggered during the Renoir bossfight.

[Kolaya]

hi.
i got issues with the combat mechanics achievements for lune and sciel (perfect flow & the one where you need to consume 20 foretell cards) during the renoir boss fight specifically. i tried to do it several times, yet the achievement is not being triggered. any explanations ?

for lune i used electrify into the earth spell that convert the thunder stacks into earth ones. for sciel i just stacked 20 foretell witth a gradient attack & consumed them all in a row with one attack with high damages.

let me know ): i would love to 100% this cool game
