Cannot find my friend in ZwiftPower Search

Why can’t I find my friend “Gary Plea****” when searching Riders in Zwiftpower.com? I go to Events, see the Riders tab, click on it, the enter his name in the Search box. I see many other Gary’s but not him.

I CAN only locate him by clicking on the results of an event he attended then clicking on him there, and can see his profile that way. I can also find him by searching his Team name and locating him there.
