The current implementation of dismantling filters prevents accessories from being dismantled if they have 1 or 2 engravings set as favourite depending on settings, ignoring the setting that specifies stats you do not want to keep.
I believe the ordering is wrong and should dismantle undesirable stats regardless of engraving settings, as an accessory with high quality and best-in-slot engravings is still worthless when tied to say expertise.
