This is less of a bug and more of a feature request, but I will include it anyway: There is no icon in Modmenu, even though all other mods have one. You can compare to the mods on either side in the attached image.

There was actually an icon, but it was black text on a transparent background, so you couldn't see shit. I've added a better icon. (Although it does kind of look shit in modmenu :/)
