Number items not updating concistently in Basic UI

I have a number item that records the current power usage of a smart plug.

In the Classic UI this number changes as updates to the item are made.
But in the Basic UI the only way I see the new values is by refreshing the browser.

Is this a known issue?

This is one OpenHABianpi using the more recent build.

I had the same problem with several item in basic I. Im using openhab openHAB 2.1.0-1 (Release Build)
I did an update of the system and everything started to work. (ssh login and so on)
I hope this helps

Same to me…
I can confirm restart helps Thx.
