Wipers not fully returning

[Wedgy]

For the last couple of days I've noticed the wipers are not completely returning to their usual position which made them almost invisible looking from outside the car. They are now clearly visible and spoil the sleek look of the car.

They should drop once they’ve been off for a while or the car has been switched off. They do tend to lift slightly during use

Are they not doing that?
