I'm going to presume you've already tried the "Force track to simple" trick and found that still insufficient. And I know you're making a request and not really asking for advice or 'tips', but I'm going to mention one anyway, which you (and others) might not have considered:

Always spend the extra minute it takes to insert the intended melody as Midi into the Melody track before you start rendering the accompanying instruments!
You can then mute it, put a "Performance track" on it (vocal or any other thing), or use it for whatever you like. But if you need to free up that channel, then don't delete the underlying midi data until after you've rendered (and frozen!) the other tracks.
Now, you may ask, why is this important if I'm only going to make backing tracks for a singer or something and the core reason is simply: The program obviously can't hear your vocal, but it can detect the midi - and it does make a difference in how the accompanying realtracks turn out. In other words, they do somewhat 'take into account' (for the lack of a better term) if the melody is there or not, or more importantly when it's there and when not, if the midi data is there. And this, for your singer, should be quite important, I would wager cool
But don't just take my word for this. Have a listen to these samples: The first is from BBox own "Artist" collection, and showcases how the accompanying piano provides this lovely flourish right after the melody. And the second sample is from a song I myself made (so the BBox crew couldn't possibly have prepared something specifically for it!), notice how the piano actually seems to be replicating the melody in part. I maintain that these cases didn't "just happen", that what you get from the Realtracks is not just arbitrary or 'random', hence my advice.

Just because you can, doesn't mean you should!
