KIbana 4 Alpha 5 Discover Page cant display properly

I just start alpha 5 and use metricbeat to ingest data into ES. Data is ingested successfully; however, kibana seems cant displayed them properly in the Discover Page.

What could be the issue?

you probably just need to expand your time range in the top right corner.

Your sense query is for everything while kibana by default only shows the last 15 minutes.

I mean when I use sense, it keeps popping up new data, however, when it turns to the discovery page, ithas quite some latency, i.e. when the data start being collected for 15 mins, then it started to display message in discovery page.
