Error with CAS details

I have gotten an unconditional offer to study at KCL and was planning on applying for my Visa ASAP. I was sent my CAS number and details which I was told to check. Under the qualifications tabs, it stated: "Qualifications: International Baccalaureate Diploma International Baccalaureate Diploma - China (2018) (Results verified online)". I, however, did not do my diploma in China, I did it in Malaysia. Do you think this is an error worth contacting KCL about or is it irrelevant?

You better contact your university

I would definitely contact the university, as the details on your CAS are very important and will line up with any documents they may ask you to provide. If the CAS states 'China', but your transcripts or Certificate say 'Malaysia' they may see it as a red flag. better to be safe. best of luck!
