This is common with acrylics, the wall is sucking the water out of the paint you've just applied. When you go over it with another pass, it picks the paint off again.
Paint the wall with an acrylic primer or sealer, or paint with a thinned out coat of Diamond Eggshell, allow to dry the correct time, paint a full coat (or two)
