Master of Doomguards Achievements Missing?

I thought it was bug or I needed to beat even more for the first milestone, but then I’ve realized that I don’t see them anywhere in the list, and I’ve beat that Master like twice, unsure if that’s the case for any other master since all others I’ve beaten have unlocked achievements properly for me.

Despite that, loving the update!

Adding to this: I’ve defeated the Master of Doom Guards twice now, and though I do see the achievement available in the “Masters” section, I am not receiving credit for it.

Game version 0.7.1
