iMovie doesn't let me add more than 10 subtitles
I am trying to use the titles function of iMovie to add subtitles for a song video. It was fine until I tried to add the 11th one that it would automatically delete itself, or delete the one before if I'm dragging around. Is there a limit of 10 titles in iMovie project? If so, how else can I add subtitles in iMovie? I have upgraded iMovie to the latest version and tried delete preferences as per previous discussion thread suggested. However, the problem persists. Please advise.
