The discrepancy between the 'forum' computer and the 'music' computer discussed in this thread might have been due to not having installed the latest update patch on the music computer, as we added more styles in the patch.

You're right it would be good for us to improve the "What addons do I have" dialog so that it makes more sense for version 2018. To check if you have absolutely all Styles and RealTracks, currently the best way is to:
1. Make sure you have installed the latest update patch, so that the program knows about all available styles and is up-to-date.
2. Check in the StylePicker and see if there are any N/A styles listed.
3. Check in the RealTracks Picker and see if there are any N/A RealTracks listed.
