Black border around elements in icon composer

I noticed in the PNG export of my icon in icon composer that there is a border around a layer of my icon.

This doesn’t show up in the in app preview, but only when exported.

My icon composer file is here: https://github.com/user-attachments/files/28973433/rootshell.27.zip

This is the 1024@2x exported image
