Tint2 taskbar icons

Hi, does anyone know how to make the tint2 taskbar follow the icon theme set in xfce? I'm on mx linux using the Zafiro-Nord-Black icon theme and set it to inherit from Zafiro-Icons-Dark, Numix-Circle, and Papirus-Dark.

If I launch from the terminal and open the tint2 setting I can see line upon line of

tint2: Could not find icon '', using default.

This is driving me mad.
