Zigbee2mqtt issue - lag with gledopto and ledvance

Hi
i am having issue with 2 gledopto gl-009, system is Hassio v. 0.113.3 and zigbee2mqtt version: 1.14.3 - CC2531 firmware 20190608

When i switch on it works fine ( led is on immediatly ) but when I switch off, it spend 10-15 s to switch off led . There is a delay 10-15 seconds to update status

Same issue with ledvance gardenpole mini lights . Both works fine if i use philips hue hub instead of cc2531 . I have switched off philips hub and would use only cc2531

Any ideas ?
