Reader shows text not in the lesson

This is private lesson, part of a course into which I imported the text of a book that was automatically split into multiple lessons. The text circled in red below is not in the text of the lesson – it does not appear in either the edit nor the print views, and is not in the original. This is at the very front of the second lesson generated by automatically splitting the input. (I haven’t peeked a the subsequent lessons to see if the issue is repeated.)

And there are extraneous, out-of-place lines at the end of the second lesson and at the beginning of the third. In neither does the misplaced content appear in the print version nor the editor.

Hi khardy,
Can you please post a link to that lesson here or send it to support(at)lingq.com so that we can check it? Thanks!
