Thanks.
I do think your instance of TD 3.7.1 is using language catalogs from 3.4.3, because I duplicated the context-menu part of pointing my version 3.7.1 at the language catalogs of 3.4.3, and it looks exactly like your screenshot. But I don't see anything in your information that would *specifically* cause this. But I do see some weird things.
For example:
Data Folder: C:\Users\jrwil\OneDrive\Documents\The Tournament Director 2
DB File: C:\Users\jrwil\AppData\Local\Programs\TheTournamentDirector\db\td.db
DB Folder: C:\Users\jrwil\AppData\Local\Programs\TheTournamentDirector\db
Install Folder: C:\Users\jrwil\AppData\Local\Programs\TheTournamentDirector
Repo Folder: C:\Users\jrwil\AppData\Local\Programs\TheTournamentDirector
OK, notice that the Data Folder is, I presume, where you have your Documents folder, which is what it should be. I don't know if you've configured Windows so that your Documents folder is on your OneDrive, or if you're using the TD's "specialfolders.txt" override. Either way, that's more or less correct.
However, it looks like you've got your Data Store inside of the install folder. This is NOT a good thing. When the TD is updated, either by updating itself or by you downloading and installing a new version, the install folder is completely deleted (along with everything in it). So an upgrade will delete your Data Store. I don't think that's what you want. You really should not be putting anything inside of the install folder. I actually ran into this issue when I added the language pack support during 3.7 beta, and I initially put them inside the install folder, until someone pointed out that their language pack was deleted when they upgraded. So keep everything out of there.
If you happened to copy stuff from your old (3.4.3 or older) TD instance to this folder, it might explain why the language catalogs are out of date. To fix this, first move your Data Store somewhere else. Then re-install version 3.7.1. See if this clears up the issue.
