Hello, sorry for the inconvenience caused.
It is not a bug. While playing a video, you can click the "File List" icon to manually select the video you want to play. Then SKYBOX will save the current video's playback progress and switch to the new video you selected.
If you click the "Previous" icon, SKYBOX will restart the current video from the beginning. Only after a subsequent click on the "Previous" icon will it switch to the previous video.
