Remove voice actors stats from audiobooks

I listen to many audiobooks/audio plays (unsure of the correct English term). These are audio stories performed by multiple voice actors. Each voice actor is credited, which floods my stats. Currently, only voice actors appear in my top stats. While I appreciate the show being displayed, it would be preferable if not every minor character was included. The show in question is 'Die drei ???'. In the picture provided, you can see that the first non-audiobook related entry only appears at number 24, despite having played only 'Die drei ???' audiobooks.
