rbenv uninstall seems not removing all

[kirankotari]

I have uninstalled 2.2.4 from my system using rbenv uninstall 2.2.4

Now when I type rbenv global it still showing 2.2.4

when I do rbenv rehash it's throwing following error
C:\Users\....\.rbenv-win\libexec\rbenv.vbs(92, 61) rbenv: version '2.2.4' not installed

$ rbenv versions
  2.0.0-p0

The original rbenv is slightly different, but it is similar behavior, so I want to close this way.
