It's a special fallback which Jupyter will always find if it can import the ipykernel package. The easiest way to 'get rid' of it is to use the name 'python3' for one of your other kernels (probably the python 3.6 one).
If all of your kernels are in separate environments from your notebook server, you can also get rid of it by removing the 'ipykernel' package. There is also a config option KernelSpecManager.whitelist, but it's a bit clumsy to use it for this, because you'd have to update it any time you add another kernel.
