Classic form layout option is not working

Hi,
If web pivot doesn't have any measure and it contains two rows and one filter then when i am setting layout as a "classic form" then its not showing second row name  in web pivot,but its working if i am setting layout as "compact " or "tabular".
Please find the below code,
function onOpenLocal() {
pivot.updateData({
dataSourceType: "csv",
browseForFile: true
});
}
function onLoadRemote() {
var filename = prompt("Open remote CSV", "https://cdn.flexmonster.com/data/data.csv");
if (filename != null) {
pivot.updateData({
dataSourceType: "csv",
filename: filename
});
}
}
var pivot = new Flexmonster({
container: "#pivot-container",
componentFolder: "https://cdn.flexmonster.com/",
toolbar: true,
report: {
dataSource: {
dataSourceType: "csv",
filename: "https://cdn.flexmonster.com/data/data.csv"
},
slice: {
"rows": [{
"uniqueName": "Country",
"sort": "unsorted"
}, {
"uniqueName": "Category",
"sort": "unsorted"
}],
"pages": [
{
"uniqueName": "Business Type"
}
],
"columns": [],
"measures": [],
expands: { expandAll: true }
},
options: {
configuratorActive: false,
grid:{
type:"classic"
}
}
},
width: "100%",
height: 400
});
