Problem with familiar bank preset with impure essence

Guys, so i had my Runecrafting banking preset with pure essence, and now i want to change to Impure essence to make necrotic runes but doesn’t matter what i try, overwritting with my abyssal titan filed with impure essence, the only thing that doesn’t save up is the familiar backpack and it always fills up with pure essence… or if i take them out the bank and get rid of them it tells me that it couldn’t find pure essence for my familiar… i even erased the preset and did it again an nothing… (im obviously ticking the familiar option)
