Additional Info.

This is caused by a blank line in the header after DESCRIPTION.
If the DESCRIPTION text entered in ERGdb/TrainerDay contains a newline at the end, this will be carried over into the .MRC and break the parsing.

Removing this blank line from the .mrc header allowed the task to complete.
