Empty tags being added

My event list page is set to use the following for the list format:

<div class="custom-event-wrapper">
<a href="#_EVENTURL">
<div class="custom-event-img" style="background: url(#_EVENTIMAGEURL)"><span class="custom-date-positioned"><span class="custom-event-day">#_EVENTDATES</span></span></div>
<div class="custom-event-title">#_EVENTNAME</div>
<div class="custom-event-time"><b>#_EVENTTIMES</b></div>
</a>
</div>

But the output is adding a <p> tag with an empty link (bit in bold). Although you can’t see it on the page, it fails accessibility due to the empty link. Any ideas how to stop event manager from adding this?

<div class="custom-event-wrapper">
<a href="https://www.domainredacted.com/events/eventname/"><p></p>
<div class="custom-event-img" style="background: url(https://www.redacted.jpg)"><span class="custom-date-positioned"><span class="custom-event-day">02/03/2025</span></span></div>
<div class="custom-event-title">Event title</div>
<div class="custom-event-time"><b>10:00 am</b></div>
</a><p><a href="https://www.domainredacted.com/events/eventname/"></a></p></div>
