I had the same issue, discussed here https://www.kincony.com/forum/showthread.php?tid=5725
Basically the integrated relays are rather small and they do not handle large currents. A lot of LED lights (especially cheap ones, but sometimes even higher-end ones) create what is called high inrush current - for a few milliseconds, you have several amps going through the switch. This is enough to fry it shut.
This is why you are supposed to use the integrated relays to drive larger external ones, or solid-state relays. You could use for instance these https://www.kincony.com/omron-din-rail-r...odule.html
You have another discussion here about this:

For my own case, I bought spare relays, I desoldered the relay from the board and I soldered a new one instead. I know now that I need to use external relays for some specific lamps in my house...
For more info you can google "high inrush current".
