All-week appointment deleted but YCBM still shows unavailable

Google Calendar within a G Suite environment. Someone accidentally sent me an “all day every day” appointment" and I accidentally said “Yes” to it before realizing it blocked me out completely for any other appointments. I confirmed that YCBM is showing “no availability” for every day for weeks. So I went and changed the invite response from yes to no, and it disappeared from my Google Calendar. But YCBM is still showing entirely “No availability” (also tested this in an incognito window to make sure it wasnt a cache issue).
I’m not sure what to do, or if the problem will clear itself in some period of time.

You need to have Google Calendar show declined events - then you’ll be able to either delete that event, or set it to “free”.

This solved it thanks!
