Order completed... But still revenues in upcoming earnings


I’m using fiverr since the last few months and have a pretty decent experience over here. But, something unusual happened to me over a last few days.

I got 2 orders from a buyer and a single order from another buyer. After completion, the buyers marked the orders as completed and also left with positive reviews but the revenue in still under “upcoming earnings”. Before this, whenever I completed any order, the upcoming earnings used to sum up with “earned” immediately. I don’t know why this is happening. Please help.
