Events- "Interested" button is missing

Just installed 13.0.0-B1 and notice that there is no "Interested" button on my event page. (image below)

After I click the "Going" button, it changes to "Not Going" then I see the other button shows up-"Not Interested". Well yeah duh.. why would I click that if I'm going. 🤔 When I do that, the button changes to "Interested" with a check mark. It looks like I'm.... interested. That whole part is quite confusing. 🤷🏻‍♂️ Is it just me or do you feel the same way? Anyway the point is, am I supposed to see the "Interested" button there before I hit the "going" button? We have plenty of people who are interested but haven't decided to go. :P
