I'm talking about Audrey's. I've been getting them at random moments it seems. Like, I already had Reflection 20, but only got the Reflection 30 after 15 or so reflected attacks.

I'm currently missing 4, the Lightning 100, which I'm willing to agree that I may not have yet, and 3 that require to kill x amount of enemies, being 15 Spinnies, 15 Stompies and 3 Owls.
Thing is, I did Audrey's first part like 6 times over, killing well enough of each, with the sword, with the lightnings and still got nothing. Are the numbers wrong ? I even tried the "old reliable" beta.

Do I need to complete all of Audrey's part each time ? Is there something I can do to get these achievements ? Has someone encountered this problem too and managed to resolve it ?

Thank you in advance to anyone answering
