In all probability, the width of the field returned from the UDF isn't uniform, and so the first resolution of the expression is seting up the maximum field legth, so that some values of the resultant cursor are truncated, or padded to the initial length of the field with trailing spaces.

Returning a variable length value from the UDF is the root of your problem.
