I've unpacked the latest TurboDB Data Exchange (Windows) from https://www.dataweb.de/de/support/downloads.html
So, the .quelea folder c:\Users<account>.quelea\ contains TdbDataX.exe

Database, Import, ZionWorx starts the dialog:

Default database setting for ZionWorx : C:\ProgramDa

Sermon Manager assumes that a comma means a new series in the series input field. That means that when a series contains commas it is broken up into several series. E.g., a series titled "Doubt, Disbelief, and Disobedience" is broken into three series: "Doubt", "Disbelief", and "and Disobedience."

Perhaps a newline marker (\n) would make a better series separator?

The person_role table, declared in server/people/models.py should be called people_person_role because it is in the People module.

Yes, that's a lot of "people" and "person," but at least it would be consistent. :-)
