Alexa does not discover correct items with Hue Emulation

Hi All,
I re-installed openhab because the old server has gone, but now, when I try to discover new devices Alexa finds always switchable device. No matter if I indicate Lighting or Switchable, it discovers only switchable items and it describes all devices as Royal Philips Electronics smart device. I forgot the old description, but I think that it wasn’t the same in the past.
My old server was Ubuntu 16.4 but now I’m using Centos 6.8 in both cases with openhab 2.4.0 and Hue Emulation 2.4.0
Someone had the same issue?
