Route Creator Checkpoints not Working

When you build (or play) a custom race, more times than not, a checkpoint will not register no matter how many times you drive through it. Meaning it is impossible to finish said race. Also when building the races I constantly get a count down for missed checkpoints for no reason. If T10 could please fix this because I really want my Crash Alley inspired track to work but the checkpoints ruin the race every time.
