So without any activity from Homey, it starts operating? That would be very strange… what shows you the ZWave dev. view? Have you tried to repair them?
…so you are using Philips Hue app - ? - [APP] Philips Hue by Athom - #386 by Daniel_S - seems someone already reported that, try to ask how this user resolved it…
I abandoned Philips Hue Bridge 3 years ago and controlling then via Homey directly, I don’t regret it - they works flawlessly for me on both HP19 and HP23.
Anyway, unless Athom is aware and working on fix, maybe you can try with Matter? I read somewhere that it’s in Beta already, isn’t it?
