There is a bug currently for displaying primes (First Over Line). See for example. events.php?zid=2417607 > Primes > B
The interface does not change the ZP_VARS.prime_type to “elapsed” but sticks with “msec” forever, thus calling the API by api3.php?do=event_primes&zid=2417607&category=B&prime_type=msec instead of […]&prime_type=elapsed.
Thanks for your work,
