2 Real people with the same name

On namemc, there are 2 new people. They are both named Bar (14f19f50-50cb-44cd-9f0b-be906ad59753 and 5a951fb1-69cf-42cb-a7b4-fdc1c3a89730). I think they got the name at the exact same time and Mojang glitched and let both of them have the same name, or it is NameMC's visual glitch, because yesterday the last time i saw is when it said the name was avaliable in 7 hours. If i made the format wrong, sorry because this is my first issue i made.
