Hmm, I have not seen this before, but that particular date gives me the same problems. Looking further ALL of the student Bible studies in the Sep/Oct mwb have the issue.
First check the Settings - Life and Ministry Meeting - 'Main' tab table to see if the talk name in the workbook, has the right meeting item connected to it. If not, correct the 'meeting item' (double click and choose from dropdown). This was OK in my case.
Then in Settings - Life and Ministry Meeting - Schedule tab, highlight the weeks in the top box one by one, and check the same connection in the bottom box. In the picture, this is already fixed. In the first column, in the student Bible study row, you should change First Return Visit to Bible Study.
While you are at it you can check the other items. And you can do all weeks for that workbook.
