deleted bang mesh still appearing in s4s

howdy!! im working on an edit of a mesh by saruin and im not the best with 3d modelling. basically, the bangs from what im fairly certain are the hat chops keep showing up as part of the model when i import it into s4s, despite the fact that they are completely deleted in blender. any way to get rid of this? i only want the long bangs over the left eye.

some pics for reference:

this is what i WANT it to look like

and this is what it actually looks like in s4s:

and here's the s4s file and blend file if that helps.

thanks!!
