primefaces selectOneMenu not outputting correctly - primefaces

Question

I am creating a SelectOneMenu. The menu outputs correctly. However, along with the menu being outputted is an InputBox and then all the items of the menu being printed as text. I don't know what is causing it. I have included a image of the output below.
Here is my JSF code:
<p:panelGrid columns="2">
<h:outputLabel for="trader" value="Trader:" />
<p:selectOneMenu id="trader" value="#{fixBean.trader}">
<f:selectItem itemLabel="Select" itemValue="0" />
<f:selectItems value="#{fixBean.traderOption}" />
</p:selectOneMenu>
</p:panelGrid>
Below is the code to my Bean:
private SelectItem[] traderOption = createFilterOptions(traders);
private final static String[] traders;
private static String trader = "";
static {
traders = new String[9];
traders[0] = "Dowd";
traders[1] = "Dwyer";
traders[2] = "Edelman";
traders[3] = "Hughes";
traders[4] = "Kelley";
traders[5] = "Nauyokas";
traders[6] = "Options";
traders[7] = "Rafferty";
traders[8] = "Russillo";
}
public String getTrader() {
return trader;
}
public void setTrader(String trader) {
this.traderOption = trader;
}
public void setTraderOption() {
traderOption = createFilterOptions(traders);
}
private SelectItem[] createFilterOptions(String[] data) {
SelectItem[] options = new SelectItem[data.length + 1];
options[0] = new SelectItem("", "Select");
for(int i = 0; i < data.length; i++) {
options[i + 1] = new SelectItem(data[i], data[i]);
}
return options;
}
public SelectItem[] getTraderOption() {
return traderOption;
}
The SelectMenu has the correct options in it however, I don't know why the rest of the output is being create (i.e. InputBox and text list).
****update****
I rebuilt the page using the primfaces SelectOneMenu example and built out from there. That resolved the issue. Though still not sure what was causing the issue
