Problem withdrawing on microworkers

Hey guys. So i've never liked this site at all, but I already has 5$ so I decided to climb up to 9$ wich states is the minimum PayPal withdrawal. The thing is, when I click, It says I don't have enought founds, even tho I have 9.05$ on the account. The weird thing is that when I click to withdraw with payoneer (min withdrawal of 20$) the error doesn't appear! Anyone knows what's happening?
