Default boundary layer problem

Hello,

For my twisted rotor blades, when I attach the boundary layer to blades walls and then view 3D boundary layer, the hex elements are ok near the trailing edge. They are round and smooth. But when i cooper this volume with one of the source face pre-meshed as Quad/pave, the same elements very near to trailing edge become highly skewed. I could not figure out why this happens. The source faces are hub and casing. I also tried using TGrid scheme with hex elements near the blade walls and tetrahedral away but still could not control the skewness of the cells. any suggestions many thanks,
