Exporting IgxGrid's data CSV sample is broken

Open the sample for the paragraph: https://www.infragistics.com/products/ignite-ui-angular/angular/components/exporter-csv#exporting-igxgrids-data

Or directly in the demos app: https://www.infragistics.com/angular-demos/services/export-csv-sample-1/


The grid doesn't display data. There is a weird data under the button.
