Anyone who knows about Microsoft Business center license?

Hi, Friends

Anyone who knows about Microsoft Business center licesne?

To clean domain from power bi admin page, I can see Microsoft Business center license, I hope to remove that account to add its domain to office 365 services, but no matter how I find that licesnes from office 365 licenses page, there is no entry, and when I ask it to my colleage , they don't know about it. 

If you want to see that license, let me show you, but it is hard to find to change language from Korean to English.
