My 9 ordinal items for the CATPCA have 4 categories, 0 1 2 and 3. They are positively skewed.
Example: variable 1, frequency table:

When I enter them into the CATPCA, all "0" are ignored. My missing values are defined properly, and I've been using SPSS on this dataset for several months now, without problems. What could cause this?
Here the CATPCA output for the variable1:

As you can see, 1 2 and 3 are matches, but 0 doesn't appear in CATPCA.
