Braces and brackets misplaced and causing the rest of the score to be blank

See attached .mscz file. Export the main score as PDF and you will see that the braces are misplaced in the top left corner and the second page of the score is blank. I have attached my copy. The workaround is to rewrite the part causing the issue---in this case, the electric bass part. However, I have this issue with a score of 26 parts and over 200 measures, and I'm not sure which part(s) is/are causing the issue, so rewriting parts is not feasible. I mainly want to know what is causing this issue and how to fix it so I can export my score to print; having it fixed in an update is a secondary priority for me.
