I have a page that gets the record type of an object and displays it in a picklist in a lightning component, but when the object gets rendered, only 2 options show up in the picklist. 
After selecting one of the options, the picklist rerenders and shows all the options. 
It is doing this for all of the picklists on the page and has the same behavior for all of them.
Below is a sample code that populates the picklist dynamically and will illustrate the issue if run in any org.
sampleIssue.cmp
<aura:component implements="force:appHostable">
<fieldset class="slds-form--compound">
<div class="form-element__group">
<h3 class="slds-section-title--divider">Product Information</h3>
<div class="slds-form-element__row"/>
<div class="slds-form-element__row">
<div class="slds-form-element slds-size--1-of-2">
<ui:inputSelect class="slds-select" aura:id="lob" change="{!c.handleSelect}">
<ui:inputSelectOption text="--Select Product--" value="0"/>
<ui:inputSelectOption text="Product 1" value="1"/>
<ui:inputSelectOption text="Product 2" value="2"/>
<ui:inputSelectOption text="Product 3" value="3"/>
</ui:inputSelect>
</div>
<div class="slds-form-element slds-size--1-of-2">
<ui:inputSelect class="slds-select" aura:id="productType">
<ui:inputSelectOption text="--Select Product--" value="0"/>
</ui:inputSelect>
</div>
</div>
<div class="slds-form-element__row"/>
</div>
</fieldset>
</aura:component>
sampleIssueController.js
({
handleSelect : function(cmp, event) {
var selectCmp = cmp.find("lob").get("v.value");
console.log(selectCmp);
var opts;
console.log(selectCmp);
switch(selectCmp)
{
case "Product 1":
opts = [
{ class: "optionClass", label: "--Select Product--", value: "0", selected: "true" },
{ class: "optionClass", label: "SubProduct 1.1", value: "SP11"},
];
break;
case "Product 2":
opts = [
{ "class": "optionClass", label: "--Select Product--", value: "0", selected: "true" },
{ "class": "optionClass", label: "SubProduct 2.1", value: "SP21"},
];
break;
case "Product 3":
opts = [
{ "class": "optionClass", label: "--Select Product--", value: "0", selected: "true" },
{ "class": "optionClass", label: "SubProduct 3.1", value: "SP31"},
];
break;
default:
opts = [
{ "class": "optionClass", label: "--Select Product--", value: "0", selected: "true" }
];
break;
}
cmp.find("productType").set("v.options", opts);

handleProduct: function(cmp, evt){
}
})
