Border problems on Event List

I am completely stumped as to why some of the borders are missing on my list of events at http://macontracks.org/events/ . I created the events all the same, so why do some of them have a border on top and others don’t? I’ve been trying to adjust the styles for hours but when I get the borders to come back on some event listings, they go missing on others. Here is the code for my table header in Events>>Settings>>Formatting>>Events

<table id="local-race-list" width="80%">

    <tbody>

and for the table body:

<tr>
	<td width="170px">
   <h4>{no_time}#_12HSTARTTIME{/no_time}</h4>
    #_EVENTIMAGE{150,0}
    </td>
    <td>
    <h2>#_EVENTLINK</h2>
    <h3>{has_location}<i>#_LOCATIONNAME, #_LOCATIONTOWN</i>{/has_location}</h3>
    <p>#_EVENTNOTES</p>
    </td>
	<td width="170px">
	<a href="#_ATT{Link to Race Website}" class="myButton-blue;" target="_blank">Go to Race Website</a>
	<a href="#_ATT{Link to Registration Form}" class="myButton-blue;" target="_blank">Download Registration Form</a>
	<a href="#_ATT{Link to Racer Pal}" class="myButton-blue;" target="_blank">Racer Pal Registration</a>
	</td>
</tr>

and here’s the corresponding css I put in my theme’s style.css:

#local-race-list table, th, td, tbody{
	border: 2px solid #b9cfe4;
	padding: 5px;
}

Since this is occurring seemingly randomly, I don’t know what to try next. I also have an issue with extra space above the titles of the two events that don’t have times, the Komen race on Sept. 26 and the Jay’s Hope race on Oct. 31. Any help would be most appreciated!
