Hi m4xspeed,
The reason the listing you posted through Auctiva reflected USD currency is because you posted those items to the eBay.com(US) website. On the other hand, the reason the listings you posted through eBay reflect the MYR currency is because they were posted to the eBay Malaysia website.
Auctiva currently only supports posting to eBay.com(US), eBay.co.uk(UK), eBay.com.au(Australia), and eBay.ca(Canada). Since we do not support posting to the eBay Malaysia website at this time, unfortunately, it is not possible to create listings that will reflect the MYR currency through Auctiva.
Any additional questions or concerns? Please file a support request using the appropriate link on our help page:
