Captions are not synchronized
Captions SHOULD be precisely synchronized to the audio, except when doing so would make captions difficult to read.
People who are deaf cannot hear the audio of multimedia (audio-video) content. In order to give people who cannot hear access to the information conveyed by the audio content, synchronized captions must be provided. The captions must include all essential dialogue, identify the speakers, and describe all essential sound effects. People who are deaf can read the captions while watching the video.
Fix this issue by synchronizing captions with the video.
