reek: Getting error when running reek

When I run reek I get this:

I removed the .reek file assuming I botched it up, but it still gives the same error. My code passes rubocop, and it does still work. Any ideas how I can figure out what the issue is? The word “name” is pretty common in the code, so that’s not much to go on.
