Availability not showing correctly for 1 meeting type

Hey everyone! I have three meeting types on my Bookings page (15 minute, 30 minute, and 1 hour). The 30 minute meeting (the most commonly used one) is no longer showing my availability correctly. It shows that I am booked up way more than I am making it difficult for people to make meetings with me without coordinating them directly. I've tried all the recommended troubleshooting. Any thoughts on what might be causing this?

TIA!
