How can I remove default version of bundler? : <p>I tried to change default bundle version but it getting updated with 2 default version. How can I modify to single default?</p>

<pre><code>$ gem list bundler

*** LOCAL GEMS ***

bundler (2.0.1, default: 1.16.6, default: 1.16.2)
</code></pre>

<p>If I do gem uninstall not removing defaults,</p>

<pre><code>$ gem uninstall bundler
Successfully uninstalled bundler-2.0.1


$ gem list bundle

*** LOCAL GEMS ***

bundler (default: 1.16.6, default: 1.16.2)
</code></pre>

<p>How can I set (like the below) default as single version?</p>

<pre><code>bundler (2.0.1, default: 1.16.6)
</code></pre>
