No rankings after a race

Hello- I raced today but no one received a ranking in the race. Is there a reason for this happening? I’ve had this happen in a race before and just curious of the reasoning

TZP Bente bente race presented by Team ODZ @5:00am MST

I also did not get a ranking.
For me it was the giant crit crushers at 6pm pst.

this is also the case in the third and fourth giant crit crusher races. why ?
