Fibaro Motion SENSORS getting stuck

I can see previous discussions on the topic, but I cant solve this problem with my Fibaro motion sensors. I have 10 Fibaro Motion sensors, Zwave plus. A couple of them, keep getting stuck in motion until either a further motion is detected or the device is updated from the online hub status.
Devices are all with a few metres from the ST Hub. Batteries are full. Other sensing like Illuminous or temperature work fine. But, Motion detentions gets stuck atleast once a day, in atleast One of the 10 sensors, and its not with just one sensor. Could someone please advise ? Is it a common problem or fault with Fibaro, or is it something wrong with my my setup. ST Hub is new, and all other devices are working spot on. Will appreciate your advice. Thanks.
