No I actually don't know that. Do you have any extra info confirming that they were standing laps (other than whats already discussed)?
Even if they are (and they very well might be), having flying and standing laps on same board doesn't make it inaccurate. Standing start is a self-inflicted disadvantage that just results in slower laptimes - nothing wrong with having fast and slow laptimes on same board.
It is only a problem once you start comparing cars.
