Dimming problem with Fibaro and Alexa

Hello all

I have installed the Fibaro Dimmer 2 and it’s connected to SmartThings and Alexa. It’s working great apart from one thing and I don’t know it it’s an issue with Fibaro, SmartThigs or Alexa.

The issue I have is when I have it a voice command via Alexa to dim down to say 50%, it works great. When I say ‘DIM’ or ‘SET’ to 100% it do not do anything, but Alexa says “OK” as if it has carried out the command. However, sometimes it does work when I say DIM or SET to 99%!! but not 100%. It works fine in both apps.

Any Ideas?
