DBMC is a distinct application, similar to Kodi, but has it's own data directories etc. The latest DBMC is currently 16.6.0, so you would need to use a Jarvis compatible build in it.
You could add a shortcut to Kodi on the right handside (look for an "Add" or +/± icon), assuming you're running the latest firmware already, Kodi will be 17/Krypton so should be ok with the build.
[edit]
Should have refreshed before posting, Nigelar beat me to the response!
