Paragraph Tag Added to Description

First, thanks in advance for your help.

Here is my markup in the plugin:
<div class="uk-badge uk-text-bold uk-text-primary">[event-title]</div><div style="color: #585858;">[if-single-day]<i class="uk-icon-calendar"></i> [start-date][/if-single-day]</div><div style="color: #585858;">[if-multi-day]<i class="uk-icon-calendar"></i> [start-date] - [end-date][/if-multi-day]</div><div style="color: #585858;">[if-not-all-day]<i class="uk-icon-clock-o"></i> [start-time] - [end-time][/if-not-all-day]</div><div style="color: #585858;">[if-whole-day]<i class="uk-icon-clock-o"></i> All Day[/if-whole-day]</div><div style="color: #585858;">[if-description]<i class="uk-icon-info-circle"></i>[description markdown="yes"][/if-description]</div>

Here is the output in my source code:

<div class="simcal-event-details"><div class="uk-badge uk-text-bold uk-text-primary"><span class="simcal-event-title" itemprop="name">No School</span></div>
<div style="color: #585858"><i class="uk-icon-calendar"></i> <span class="simcal-event-start simcal-event-start-date" data-event-start="1461326400" data-event-format="D, M dS, Y" itemprop="startDate" data-content="2016-04-22T07:00:00-0500">Fri, Apr 22nd, 2016</span></div>
