Duplicate Bone names,How to find duplicate bone names?

I am rather new to unity and I am trying to add expressions onto a vroid model. Every time I go to export the model it pops up; 'Find duplicate Bone names. Please check model's bone names.' Well I keep looking and I have not find a single one yet. Is there a certain way of finding it (besides literally nitpicking through it like I have been). And a way to fix it? ,I am rather new to Unity and I keep popping an error before I can export a Vroid model "Duplicate Bone names. Find Model's duplicate bone names." Well its been 6 hours of me trying to figure out what bones are duplicated and have been unable to find them. Is there a certain way of finding this?
