Zwave switch not work in Groups, but do so as single unit in GUI

[Hass-IO, RPI3, Aeotec Z-wave stick Gen5]

Hi there, I had a setup that been working fine for at least two years, but recently some switches fail to switch when in Groups, like “all-outdoor-lights”. They do switch when i switch them individually in GUI. No changes has been made in the setup, only update the Hass.io every month or so. Any ideás or thought what has happened? Seems like i lose a switch (through Groups) or two every time i power cycle the RPI.
