Personal info on Apple pay

My Apple Pay info keeps loading my ‘nickname’ as my contact name when I try to use Apple Pay on my phone. Which means transactions won’t go through unless I manually change it to my real name and last name.

I’ve gone though my wallet details and even been on my Apple ID page and tried to find how to fix it, but I can’t seem to be able to rectify this as it all appears to show my correct name, so I don’t know where my phone is getting this information from.

If anyone knows where I can go to fix this issue, I’d highly appreciate it.

Thanks
