Problem with a race not showing in zwiftpower

I’m a zwiftpower registered user and have been participating in many zwift races without any problem with ZP so far.
I’ve participated in the Newbury velo midweek TT yesterday (wednesday the 19th - 8 PM european time), and the event is not showing in ZP which is very odd. This is a first for me.
Does anyone have a clue what’s going on ?
