I can’t remove a video effect

Is anyone really good at CapCut and can help me figure out how to remove a blurred effect? It doesn’t show up for me to remove it. It’s only showing the zoom lens which I put on there to try to remove the blurred effect. But if I change it to none… it still shows the blurry effect. It’s like the video effect is frozen in time at the 8 second mark. If I add a video or remove one… it always show the blur at 8 seconds
