Oh yes very clear, I am a decent user of db master, and fifa editor so I have an understanding of how they work, unfortunately I dont have the project files for the mod so I wont be able to do this, although it seems quite straightforward to me. thanks anyway, I'll keep this for future useAlright.
First, you need to have DB Master to be able to open the db.
Now, in your Fifa Editor Tool, head over to Legacy Explorer and navigate to >>>data/db<<<< then extract fifa_ng_db.db and fifa_ng_db-meta.xml into a folder of your choosing.
Next, open DB Master and point it to the directory where you extracted the 2 db files and open the db.
Once inside the db, find the nations table and look for the column titled confederation.
What you need to to is make sure that all the African Countries have their confederation set to 3, which is the value for CAF.
This way, the confederation assigned to each tram will match the tournament configuration for the tournament you're playing so you should be able to see the standings now.
If this doesn't work then it means the tournament wasn't set to the CAF confederation in the first place so you'll have to confirm with the modder as to which confederation he put the tournament in so you can adjust the team confederations to match it.
Also, I'm not sure if the modifications will work with existing career mode or if they won't be affected by the other mods you have installed but you could always move the mod to the bottom im Fifa Mod Manager to give it priority.
I hope I was clear enough, cheers
