Oh, and if maybe the problem is with what I have in the actual button code block text, here's how that looks:
<div class="sqs-block button-block sqs-block-button">
<a href="#" data-featherlight="#tuesdayues" class="sqs-block-button-element--medium sqs-block-button-element">Tuesday Uptown: Laid Back - Soft "No-Sting" rubber Balls</a>
</div>
<div style="display:none;">
<div id="tuesdayues">
<p> <p>
<strong>When:</strong> COMING SOON: TBD - NOT YET OPEN
</p><ul>
<li>NYC's only "No-Sting" rubber ball league
<li>NYC's classic format for years. Sign up solo or in small groups together and we make the teams out of that. That’s what makes this league special and popular:</li>
<li>Great for newbies/if you suck/vets – every team will have a mix of all, so you’re good!</li>
<li>Teams are made even so everyone’s got a chance each week</li>
<li>Every season we pair different friend groups together so there are never any cliques. Everyone meets everyone. Which is why it’s become the best sports <i>community</i> in NYC - instead of just 10 team cliques by themselves</li>
