Calculating average velocity for planes - Confused!

I'm fairly new to CFD and have had to learn rather quickly.
I'm currently trying to compute the average velocity on a number of planes of differing heights in my model.
For each height in the model, I have created 4 planes - 2 small equally-sized strips running along the far edges and 2 larger equally-sized planed in the middle. Please see the screen shot below for clarification, each plane is a different colour.
I have entered the formulae for average velocity for each of these planes, but I'm getting identical numbers for the 2 small strips and equal numbers for the 2 middle planes, despite there being an uneven velocity distribution along the x-axis, see second screen shot.
The planes are slice planes, and have tried changing them to sample planes and varying the sample points, the numbers change but are still identical. I must admit however that I'm struggling on finding out precise definitions of these and the help literature is quite sparse.
QUESTION: What am I doing wrong to get identical values for these clearly different regions?
Apologies if this is a completely obvious question- I've not been given much time and support with this.
Thanks in advance!
