<p>I recently answered <a href="https://stats.stackexchange.com/a/635224/2958">a question</a> using the following code</p>
<pre><code><span class="math-container">$$\begin{array}
\mathbb P\Big(X = \mu+\frac12\left(\gamma+\sqrt{4\kappa-3\gamma^2}\right)\sigma\Big) &amp;=&amp; \dfrac{\sqrt{4\kappa-3\gamma^2}-\gamma}{2\sqrt{4\kappa-3\gamma^2}(\kappa-\gamma^2)} \\
\mathbb P\Big(X = \mu\Big) &amp;=&amp; 1-\dfrac{1}{(\kappa-\gamma^2)} \\
\mathbb P\Big(X = \mu+\frac12\left(\gamma-\sqrt{4\kappa-3\gamma^2}\right)\sigma\Big) &amp;=&amp; \dfrac{\sqrt{4\kappa-3\gamma^2}+\gamma}{2\sqrt{4\kappa-3\gamma^2}(\kappa-\gamma^2)}\end{array}$$</span> 
</code></pre>
<p>and saw a difference in the <span class="math-container">$P$</span> and <span class="math-container">$\mathbb P$</span> at the start of the first line of the array compared to the second and third, looking like this trimmed image</p>

<p>In full</p>
<p><span class="math-container">$$\begin{array}
\mathbb P\Big(X = \mu+\frac12\left(\gamma+\sqrt{4\kappa-3\gamma^2}\right)\sigma\Big) &amp;=&amp; \dfrac{\sqrt{4\kappa-3\gamma^2}-\gamma}{2\sqrt{4\kappa-3\gamma^2}(\kappa-\gamma^2)} \\
\mathbb P\Big(X = \mu\Big) &amp;=&amp; 1-\dfrac{1}{(\kappa-\gamma^2)} \\
\mathbb P\Big(X = \mu+\frac12\left(\gamma-\sqrt{4\kappa-3\gamma^2}\right)\sigma\Big) &amp;=&amp; \dfrac{\sqrt{4\kappa-3\gamma^2}+\gamma}{2\sqrt{4\kappa-3\gamma^2}(\kappa-\gamma^2)}\end{array}$$</span></p>
<p>What might have caused this?</p>
