Signups not showing

None of my events that I have registered for are showing up in Signups.
Actually nothing is listed under Signups.

How far out were the events? And could you see them on the event signup screen?

Some are now starting to show up but not all. Surprisingly the farthest one out is showing. They do show up on the Zwift companion app.

I have similar issue. For instance this event, ID=3340173. 27 have signed up and is showing on Zwift, but ZwiftPower has none
