It's not only you, same for me all the time. This happens often, with pretty much all kinds of different sports.
I guess they sometimes don't update the menu even after some games ended. I have seen this for years and guess they never really intend to fix it somehow.
Its not about updating after the event ended. In that case, you can see that the game has ended. Its about an event actually happening but not showing up to some users?(im assuming) or everyone for some reason. It showed up on live section as a game started and was the first game of the day, so can't be that of a recently ended event. Other sportsbooks, the event shows up with odds and everything but on stake its a ghost event. Some remnants of it on the live section, suggesting that a game is ongoing but the game isn't actually loading or showing up.
