Have you tried unchecking subtitle track on the subtitle selection menu/window?
There is a speech balloon button on the upper right corner of the playback screen. Click it and uncheck subtitle track.
Also you can enforce subtitles not to be displayed on the startup by unchecking Settings > Subtitle > Enable subtitles or Enable embedded subtitles.
