I produced a 3 minute slide show with 20 or so Video Collages of images and videos with text titles for each one on track 2. (See Screenshot 2) I then tried to add some background music ("After All" in the Pop section) that was around 1 minute 30 seconds long to track 3, and I used the "Smart fit for duration" tool to make the audio fit the slide show. (See Screenshot 3) Instead, it pushed most of the slideshow items ahead one and a half minutes. (See screenshot 4). I tried another short 1.5 minute titles with the same result, but when I tried to add a 3 minute audio file without using "smart fit", it worked fine. Is there a bug here, or am I doing something wrong?
