Problem with Orientation of Replacement Items

Dear All

I have put replacement items (Polygons or Rectangles) into a list of Circles on a surface.
However, the replacement items seem to vary in orientations randomly as seen in the attached file.

I have used Ramdom to select the Indexes to be replaced but I don’t think this Randomness will affect the orientation of the replacement items, most grateful if someone can point out the problem here!

Many thanks in advance!
