<p>My understanding was that when a tag B is made a synonym of tag A and merged with it, then if B had any tag wiki excerpt it would not be visible anywhere anymore.</p>

<p>However, this apparently did not happen after <a href="https://stats.stackexchange.com/questions/tagged/mixed-anova" class="post-tag" title="show questions tagged &#39;mixed-anova&#39;" rel="tag">mixed-anova</a> was made a merged synonym of <a href="https://stats.stackexchange.com/questions/tagged/anova" class="post-tag" title="show questions tagged &#39;anova&#39;" rel="tag">anova</a>:</p>

<p><a href="https://i.stack.imgur.com/86XzS.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/86XzS.png" alt="enter image description here"></a></p>

<p>The excerpt for <code>[mixed-anova]</code> is visible, despite it being merged (see <a href="https://stats.stackexchange.com/tags/synonyms">https://stats.stackexchange.com/tags/synonyms</a> to verify that it is merged i.e. has 0 threads in it ). Moreover, even though it is visible, there is no <code>edit</code> link on mouseover, making it impossible to edit or delete it. It is a ghost excerpt!</p>

<p>(For comparison, the screenshot shows the <code>edit</code> link for <code>[meta-analysis-mixed-effects]</code> which is a synonym but is <em>not</em> merged; I was mouseover-ing it when I did the screenshot. Cf. <a href="https://stats.meta.stackexchange.com/questions/4851">Can I find excerpt/Wiki of a tag that is now a synonym of another tag?</a>).</p>

<ol>
<li>Is it indeed a bug that the wiki excerpt is visible?</li>
<li>If not, then is it a bug that the <code>edit</code> link is absent?</li>
<li>If not, then how can one edit or delete that wiki excerpt?</li>
</ol>

<p>I am guessing that if one knew the tag id, one could manually try to access the edit page like this one: <a href="https://stats.stackexchange.com/edit-tag-wiki/3799">https://stats.stackexchange.com/edit-tag-wiki/3799</a>. But how to find out the tag id?</p>
