Anthurium Drooping Over After Being Re-Potted

Hope someone can help please, I re-potted my daughter's Anthurium
(flamingo flower plant) about a year ago and also took a cutting at the same time.

The problem is that although the plant is healthy and even has flowers, it drooping
over to one side, almost if it needs staking to keep it up-right (never seen them staked
before), I have also noticed that the cutting (again looking healthy) is also
dropping over as well.

I tried turning the drooping side away from the light hoping that the learn would correct
itself...but no joy...........I got to thinking that maybe I have not planted it deep enough
in the compost or maybe I have used the wrong compost, any thoughts please.

 

Assuming that it is getting enough light it has to be the compost surely? One thought - do you mist the leaves? Might be worth a go.
Not much help though.
