CLUTTERFUNK? It's impossible with flags

[GatosoNegroso]

After completing CLUTTERFUNK? with flags, when I return to the bonus levels section it shows that I have 0% progress in CLUTTERFUNK?. I completed other bonus levels but none of them have this error.

1. Go to 'Bonus Levels'
2. Click on 'CLUTTERFUNK?'
3. complete it
4. Error

I think the error occurs because the level uses coins and skateboard scores, but that doesn't happen in FUNKY ADVENTURES (I think that's what it was called).
