When i run video, subtitles automatically appear in center of a video instead of appearing below with 35 offset. When i reposition it with shortcut Shift + Up and Shift + Down it goes to normal place. How can i fix it so subtitles will appear to normal place instantly when i load the video? (also it happens for some subtitles, not all of them and i fix all subtitles with SubtitleEdit program before opening them).
