Help with custom kit graphics [SOLVED]

I'm just about to start a second season with my created club and I fancied a change of kit to make it look a bit better

I found some templates, messed around with the colours and got them ready, I then edited a config.xml from a kit pack that I found online and added it into the /graphics/kits/ folder but it isn't working?

I've tried everything and I just can't seem to get it to work

The unique ID is 8325133

I can upload the files for the kits and the config if it help

Thanks in advance for the help!

SOLVED

I managed to find a fix for the issue, everything was correct that I had prepared the only issue was with the game itself

To fix the problem, I had to use a real time editor (I used FMRTE21) to enable a setting called "allow licensed kits" I tried enabling this using the official in-game editor but after testing I realised it wasn't working but after I enabled it in FMRTE21 and saved the game then reloaded the kits they showed up
