Usingen square brackets in titles is not a good idea. Use round ones like I did.

The monastery is not consistent here, they might be rendered as links when the titles are listed elsewhere.

I think you've been bitten by side effects meant to avoid this.

Now trying: (​)

Update

For clarification: a title is supposed to be verbatim like a code section.

That means escaping of any

Unfortunately and inconsistently are node titles sometimes listed in templates without escaping these markups <>&[] leading to false interpretation.

Even the documentation here is misleading, like one help node suggesting to introduce [OT] for off topic title.

in thread What are the formatting rules for the "Title" of posts? by kcott

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
