xml date not importing correctly

I’ve been trying to open an xml file with libreoffice calc, but the dates are coming in as the date base, so I assume they are being read as 0 somehow. Here is the xml file’s style for the cells in question, and an example of one of the cells. Is there a way to fix the style so that the dates show up correctly?

Style:

<ss:Style ss:ID="General Date">
<ss:NumberFormat ss:Format="m/d/yyyy"/>
</ss:Style>

Date:

<Cell ss:StyleID="General Date">
<Data ss:Type="DateTime">2019-10-07</Data>
</Cell>
