another problem with szcz bot... pls answer

Hello again,
Now I have problem with attack mobs... Bot after kill 2-10mobs starting to stay, using imbue all time, and on right-down corner appear communicate : "the selected item cannot be used together, or the skill is already in use" what's wrong?

when u start never do the buffs urself let the bot do the buffs cuz if u buff b4 u click start the bot isnt gonna recognize ur buffs already activated and everytime it kills a mob its gonna sit and try and buff even tho u already buffed
