Created Club Logo Problems!

I am after a little help!
I have created a team and have a badge which i followed a video on how to get it into the game, but for some reason I just can't get it to work.
I have tried to have a separate folder with in the graphics one, i have also tried to include them in my logos megapack folder and even edited the config file as well, but yet the logos do not appear.
If someone could give me some advice then it would be greatly appreciated.
I am using an iMac running High Sierra 10.13.5
