Text Not Working in DaVinci Resolve

I'm currently using the free version of DaVinci Resolve 15, and I'm trying to place text over a video. When I insert the text, it appears in the thumbnail and in the timeline, but as soon as I press play on the video, the text disappears for seemingly no reason. Has anyone else been experiencing this issue? Any possible fixes would be greatly appreciated. (It's honestly probably the most obvious thing that I'm just missing somehow). Thanks!
