Jasco dimmer switch LoadLevelStatus & LoadLevelTarget not accurate

Hi - i’m trying to create an IOS app to control my dimmer switches. In playing with this I noticed that if turn on/off the light and it is reflected correctly in the UI (both my app and in the UI5 UI), and when I set the dimmer status via the app it shows correctly, however, when I use the physical light switch to set the dim value (i.e. change from 100% to ~50%) neither my app nor the micasaverde UI get updated.

Is this a known issue with the Jasco dimmer switches?
