Leviton zwave dimmer not working with Alexa

Hi, new user here. I did successfully have alexa working well with my ST hub for abit, until I decided to update the DTH for the leviton Zwave dimmer from the generic one to a custom DTH I found published on here. This dimmer now works better with the ST hub(I now have access to all the features of the dimmer), but now Alexa does not recognize it. Is there anything I can do to resolve or fix this, besides going back to the generic DTH for the leviton dimmer switch?
