Thank you for your post. Within the config directory of the application we have defined all of the generators as XML and set various properties which are loaded when the application starts.
For Business IDs (Ids.xml), we have a setting saying what to match the generator to. For this generator, it is:
" <matches field="ID" score="5" /> "
As width contains ID within the field name, the generator is automatically matching to the field name.
You can modify this by removing the configuration, I'll investigate the matching more to see if it can be improved.
