Please HELP me to change the IMDB Profile name.

Can someone please help e to change the name Artist IMDB profile. Here is the IMDB profile. https://www.imdb.com/name/nm12102865/  Please change the name from K. Buzz to K Buzz (there is no full stop or point (.) after K)   It can be verified from the sources, Sources: https://muziquemagazine.com/k-buzz-talks-about-love-for-his-craft-attributes-and-more/  ; http://www.hitsyoulove.com/2020/01/22/k-buzz-shares-his-greatest-challenge/ , https://www.blackmutu.com/2019/09/listen-to-hennyting-by-k-3u77-featuring.html  When I try to change it says, 'Buzz, K' ends with an uppercase letter and is therefore invalid.PLEASE HELP
