Auto-generated closed captions don't line up with text

When I use notes to generate audio / closed captions, I have to go back into the closed captions and redo / split almost every caption because they are not placed on the right line.  There will be audio in the next sentence show up with the previous sentence. 

Is this a common error?  Is their a fix for this?  It's several hours of extra work to ensure the cc look appropriate and correct in this regard.
