Under Preferences, in the analysis tab, there is an option to switch OFF (remove check mark) the option to “allow key analysis on import”.
Default RB will do key analysis when you import tracks. And RB will not analyse in Camelot format.
And that means you end up with regular key info in the key column of RB. As far as I know it won’t automatically “translate” regular key to camelot and there is no option to pick what key format you want to display. It will just read what’s in the key column and display that. And if you let RB do the analysis, as said, it will write regular key notation to that column.
So to get the desired result in RB, you want to switch of the key analysis on import. Now RB will just read what is in the key tag, which would be Camelot in your case and it will show it as such.
Hope that helps some.
