The model name 'Wta' was recognized as a plural, using the singular 'Wtum' instead

Question

I generated a model for Wta (women tennis association) and this is what happened:

asarluhi@home:~/workspace/tennis_project $ rails generate model Wta ranking:integer name:string points:integer
Running via Spring preloader in process 8875
[WARNING] The model name 'Wta' was recognized as a plural, using the singular 'Wtum' instead. Override with --force-plural or setup custom inflection rules for this noun before running the generator.
      invoke  active_record
      create    db/migrate/20161217102926_create_wta.rb
      create    app/models/wtum.rb
      invoke    test_unit
      create      test/models/wtum_test.rb
      create      test/fixtures/wta.yml

So rails, without prompting me with a choice, solved what it perceived as an issue singularizing Wta into Wtum: that's horrible!
What choices am I now left with: changing all those files and inside code or deleting them by hand and re-generate the model with option --force-plural?
