It looks like there is one practice section missing. Between jam_f and main_riff_2b there should be main_riff_2a. Currently, the jam_f section extends into the main riff and breaks the pattern of 4 measures per section, being twice as long.
Additionally, there are actually two sections named main_riff_2b. The first one is before the "jam" parts (shown below) and the second one is after the "jam" (shown in the first screenshot).
To fix that, the sections after the "jam" should probably be named main_riff_3a, main_riff_3b, main_riff_4a, main_riff_4b and ending.
