Why can't I batch some draw calls?

Why can't I batch some specific draw calls? they seem to be out of order in the frame debugger for some reason, and my draw call count is multiplied by a lot

The materials shown in the image are GPU Instanced, either Standard Shader or one of my custom shaders w$$anonymous$$ch is also GPU Instanced

All the models shown here are not marked as static, since I need them to be able to move, but they should qualify for dynamic batc$$anonymous$$ng. It also has not$$anonymous$$ng to do with the object count, since I don't have more than 500 instances (not even close)

Thanks a lot!
