Error with material theme

noten@noten:~/polybar-themes$ ~/.config/polybar/launch.sh --material
error: /home/noten/.config/polybar/material/config.ini:134: Value '"Material\-Design\-Iconic\-Font:size=13;4"' of key 'font-1' contains one or more unescaped backslashes, please prepend them with the backslash escape character.

there seems to be a minor issue with the material theme

I tried changing the font-1 = "Material\-Design\-Iconic\-Font:size=13;4" line but it kept breaking the text.

I think if I put the material design iconic font as like the last font then it works, but the error is still there
