2018 balance does not fit my 2018 Earnings and I haven't spent on Envato Market

When I make a 19 USD sale, I’m suposed to get 6.75 USD, but for some reason sometimes I earn like 2 USD. This had happen several times and my balance does not fit with my earnings on 2018. I haven’t spent any dollar on envato market. Does someone knows whats going on?

BALANCE: 338 USD (on 2018 only)
2018 EARNINGS 436 USD

Maybe the envato team could give me a hand? Thanks in advance

Best

Hello

It could be because some authors from countries that not have a tax treaty agreement with the US get an extra cut when the purchase comes from there. Have you seen " US Royalty Withholding Tax" in some purchases in the statement tab?
