UPG - on age cat event!

I did the Spanish Sunday Paella Rice by PETA-Z this morning and got UPG! So i’m cat B but being that i’m 48 i entered as a D as that was 40 - 49 (approx) age group. Looking on Zwift power hardly anyone in the event is listed. So i’m guessing this is an error. Can this be looked at and rectified please?
