SPSS Statistics

I am doing a Conjoint Analysis, but in the outputs the standard error of every part worth utility is the same which should not be the case as far as i know. Also with some datasets i get a Kendall-Tau of 1 despite the respondent rankings in the data set are not similar. I follow the exact steps that every Youtube tutorial shows. I create a orthogonal Design and use the following Syntax: 

CONJOINT PLAN ="C:\Users\Besitzer\Documents\Thesis\Unbenannt3.sav"

                    /DATA ="C:\Users\Besitzer\Documents\Thesis\zuverlässig.sav"

                    /RANK = Card1 To Card8

                    /SUBJECT = Id

                    /PRINT = SUMMARYONLY

I dont get any error messages, just wrong outputs. Can someone help me?

Hi. Just FYI - I have forwarded this question on to one of our statisticians, who will take a look, and may have questions.
