Final Cut Pro 12: Blade tool removes title text
Since updating to Final Cut Pro 12.0 yesterday, the blade tool is malfunctioning. If I use the blade tool to cut a title in the timeline, intending to add more text to it from the cut point on, text that was in the title previously disappears in the new portion beyond the cut point.
I am creating a video that behaves like a PowerPoint presentation, with bullet points and other text appearing as the narrator says the words. Each line of text is to remain visible as new lines are added. The easiest way to do this is to place a title that spans the entire timeline, create cut points where additional text is to be added to what was already there. It has always worked properly, until I upgraded to version 12 yesterday.
I have noticed that if I press Ctrl+Z to undo the cut, then cut again, it works...nothing is lost. But I have to do the cut, undo it, and redo it practically every time. Double-clicking the title in the timeline with the blade tool (instead of single-clicking) seems to also prevent the removal of text that was present ahead of the cut point.
I've tried a complete shut-down/restart to the computer, but that didn't help. I've made a Screen recording.
