What makes you think anything is wrong?

It did what you asked.

proc rank data=sashelp.cars out=ranks;
  var cylinders;
  ranks ranking;
run;

proc freq data=ranks;
  tables cylinders*ranking / list missprint;
run;

The FREQ Procedure

                                                 Cumulative    Cumulative
Cylinders    ranking    Frequency     Percent     Frequency      Percent
-------------------------------------------------------------------------
        .          .           2         .               .          .
        3          1           1        0.23             1         0.23
        4       69.5         136       31.92           137        32.16
        5        141           7        1.64           144        33.80
        6      239.5         190       44.60           334        78.40
        8        378          87       20.42           421        98.83
       10      422.5           2        0.47           423        99.30
       12        425           3        0.70           426       100.00

                          Frequency Missing = 2

So the lowest non-missing value is 3 and it is rank 1.  The next lowest value is 4 and it appears 136 times. So the average ranking for those 136 observations in 69.5, etc.

If you want it do do something else then tell it that by changing the options.
