Rails 4 + Datatables: Empty table displays strange double text - css

Question

I have a DataTable in my view that displays strangely when the table is empty. Every other row has what looks like an offset text-shadow but I don't see anything in my css that would do that? This issue also goes away once there is an additional column on the table.
html (example of first row with double-text "Current Weight")
<tr class="profile-row odd" role="row" data-dt-row="0" style="height: 30px;">
<td class="profile-header" data-dt-row="0" data-dt-column="0">
Current Weight
</td>
</tr>
css
element.style {
height: 30px;
}
.profile-row {
padding-bottom: .25em;
text-align: center;
}
* {
box-sizing: border-box;
}
user agent stylesheet
tr {
display: table-row;
vertical-align: inherit;
border-color: inherit;
