There were some changes made to the database entry for this device in October 2018, which is several months after the 2.3 release. I’m not sure if the changes are relevant to the problem you’re having, but they do seem to involve the command classes that would affect the switch channels.
I’m not sure what to suggest. I suppose you could try updating to 2.4 stable or 2.5 M1. If you decide to do that, you need to delete and readd all your zwave things as described here. Given that degree of change, a backup of your 2.3 installation would be a good idea in case you need to go back.
