Hi, there,
You customers were probably from EU countries.
CGTrader has recently moved to charge VAT to the customers instead of sellers: https://www.cgtrader.com/forum/topics/cgtrader-updates-vat
Therefore, the VAT column wasn't needed anymore, and the royalty rate count was adjusted to show the information without the additional VAT column.
There will be no more 58-59% royalty amount, as you will not be able to get less than 70% royalties on your sales.
Hope this helps!
Eddie, CGTrader
