Clarification Needed on Subscription Fees for Professional Seller Across US, Canada & Mexico

Hello everyone,

I am a Professional Seller on Amazon with the North America Unified Account, which includes selling in the U.S., Canada, and Mexico.Recently, I noticed my subscription fees show as three separate charges:$47.59 USD, 16.21 CAD and MX$324.35. From what I understand, the Professional Selling Plan costs $39.99 USD/month plus VAT. The $47.59 charge matches the $39.99 plus 19% VAT (I am based in Romania), but I’m unsure why there are additional subscription-like fees in Canadian dollars and Mexican pesos. Is Amazon splitting the subscription fee across marketplaces with local taxes? Or am I possibly being charged multiple subscription fees?

I’d appreciate any insights or explanations from other Professional Sellers or Amazon support reps to help me understand if this is normal or if I should contact Seller Support for a billing review.

Thanks in advance for your help!
