Font Awesome Icon in Navigation gets cut off

[Mikes-Git]

On navigation elements the Font Awesome 5 get cut off on bigger icons
Example:

fas fa-building
fas fa-store-alt

Maybe there is a radius in the CSS?

css code injection does not work in the administration for this, front end css works

.v-avatar {
  border-radius: 0!important
}
.v-icon.v-icon {
  font-size: 20px!important
}

You should be able to use the sizing classes built into Font Awesome to resize natively fa-sm or fa-xs
