For a polar array use simply Modify -> Rotate, not Move/Rotate or Rotate two.
E.g. for a 6 hole flange pattern, draw the first circle, then rotate, check multiple copies = 5 and 60° rotation angle.
This creates a 6 hole polar pattern, assumed that you select the correct rotation center.
For X/Y Arrays create a block. Then on inserting this block you can specify X/Y counts and offsets.
