New Weather Underground Plugin Duplicates text

I setup this plug in in a content page using the following short code:

[wunderground location=”Toronto, Canada” layout=”table-horizontal” hidedata = “search,date”]

Works fine except that the details are duplicated for every day.

Overcast with rain showers at times. High 16C. Winds ESE at 10 to 15 km/h. Chance of rain 60%.

This plug in is straight out of the box (no mods).
