Search Criteria not working in POWL

Hello Experts,

I have added the new fields in POWL Search Criteria using the Add custom field to SC and POWL.

but after adding the fields when i try to search using the input made by the user the resultant output is always blank and also there is no data being displayed in the newly added columns.

Please help me so that the correct output gets generated after the user input and the newly added columns are not empty.

thanks.
