So a guy from the Riiconnect 24 discord server found a tool online that changes the region for the save
https://www.tt-rec.com/ghostmanager/ on this website you take the save file and in this case, I wanted to take the NTSC save file and make it work on the PAL version of the game
So what you do is take the rksys.dat file from the NTSC save that I got from extracting and put it on the upload it to the website and then change the region as shown here on the picture to EU and simply download the file.
After that take your PAL save that you also extracted which in my case is a clean save with 1 cup completed
and just paste the downloaded file into the folder of the PAL save on the SD card.
Take the SD card back into the Wii and install the save from Save manager GX and start the PAL version of Mario Kart Wii
And now the NTSC save should be on the profile select screen with 1 cup completed
All I can say is that it worked for me and it also works the other way around like PAL to NTSC etc
So I can safely say that this issue is RESOLVED
