I really wonder about BLACKPINK’s ‘Born Pink’ first week album sales

BLACKPINK just released their 2nd full album, and I really don’t understand their first week album sales

BLACKPINK’s first week sales were 2.14 million copies on Circle (Gaon), but they only sold 1.54 million copies on Hanteo

What’s the difference between their first week album sales on Circle and their first week album sales on Hanteo? I really don’t get it

Anyway, they’re #1 on the list of highest first week album sales of all-time for Kpop girl groups

Can you guys explain this?
