Setiing ability points in my passive tree to second weapon set on xbox series x

Hi there

i cant get it. Pressing a doesent work for me. How can i set ability points in my passive tree to my second weapon set? I have a shared wand, i.e. im only using one weapon....for both sets so to say. Thank you guys. Appreciate your kind help.Im on xbox.

you need at least one weapon in each slot..

sharing one don´t work..

if you switch weapon set with bound skills or with keybindings the correct tree will get activated..
