WO71 flattener spacings

Hi folks, I am using the WO flattener that came with the second hand WO 71 scope. The diagram on the WO website pictures a 68.32? mm spacing for the flattener. Given a DSLR is 46mm BF, I tried with a 20mm spacer and had elongation of stars on the right hand side and lower corner, then added a 10mm spacer and got the same but on the left hand side?
Anyone have a similar set up they can advise?
the flattener is the 0.8 WO Flat 6A but it doesn't say on it "for the WO71" like the one on their website does.
Camera is 5DmarkII.
Cheers
Graz
