Zwave one way communication

I’m running OH 2.2.0 on ubuntu and have a strange problem. OH can control all my zwave devices just fine. But if I manually change the status for example of a wall power outlet the change in status doesn’t reflect in Paper UI. Sensor data doesn’t update status in OH any longer. This is a new problem, it did work for a couple a days ago. I have a Aeon Labs z-stick gen 5. How can I solve this problem, thanks in advance.
