events_list_grouped shortcode shows wrong day

Event days are one day off. I’m using UTC -6 in both the plugin and WordPress settings. In the WordPress settings, though, it shows my local time as one hour earlier than it actually is.

Here’s the code:
<p>[events_list_grouped mode=”daily” limit=”100″]
<div style=“float:left;margin-left:20px;”>#_EVENTLINK
#_EVENTTIMES on #_EVENTDATES at #_LOCATIONNAME</div>[clear]
[/events_list_grouped]</p>
