Version 99.  In the "enclose values with" use a value such as "#".  Now # prefixes every value, but in the process truncates the first letter of every value.  For instance, if the value is "Financial" (in my case I'm pulling the value from a grid), the pop-up list only shows "inancial" and once selected, shows "#inancial" in the column.

 

This only happens when "enclose values with" is used.  As soon as it's not used, the pop-up values are no longer truncated.  I predict this will be "fixed in V99a!"
