Unable to find table column for character data type in person legislative DFF

Summary:

Hello All,

While creating Descriptive Flexfield: Person Legislative Attributes, requirement is to create character type questions as the response consists of character type list of values. While creating DFF, we reached upto 'ATTRIBUTE30' for character data type. Now I need to create 5 more DFF but now we are not able to search table column for character data type. Please let me know if anyone has faced similar issue and how to achieve this?

Thank you,

Anuradha Singh
