Inconsistent number of faces

I want to create a axisymmetric mesh consisting of a wedge-part with a block added on the outer side. I need this to get two different patches on one side, to be able to realize two velocityfields and two boundaryconditions there.
Can anyone give me advice? Thank you!

Attach your blockMeshDict as well.

Thanks you for the answer!
In the meanwhile I solved the problem - it's all about the order of the vertices in the hex-blockdefinitions. Also you have to keep the same kind of order for every block, even the starting point of each patch (in the hex-def.) is important.
