The odd thing is it only happens to this one CPE. I have about 5 other CPE (all with the same configuration as the problem CPE) specific presets that set InternetGatewayDevice.LANDevice.1.WLANConfiguration.1.Enable to false with no issues.

It's a problem in preset handling where a value set through the "set" configuration doesn't override (or be overridden by) the "add_object" configuration. The reason why the value is not flopping in inform is due to caching. When you do a get manually the cache is cleared and the presets will cause the value to change.

What you should do instead is create another object with the same keys but with Enable set to false. Then switch between the objects using presets. But... I think there might be another bug that prevents you from doing that either :)
