For Example

  selectedOptions = [
    {
      id: 2,
      name: 'Children'
    }
  ]
        this.filteredTableData = this.tableData.filter((pdo) => {
          return pdo.pdo_advocacies.some((advocacy) => {
            return advocacy.pdo_programs.some((program) => {
              return selectedOptions.some((option) => {
                console.log(option.name);
                console.log(program.program_category?.name);                
                // Check if program_category is null or undefined
                if (program.program_category === null || program.program_category === undefined) {
                  // Check if the option name is 'null'
                  return option.name === 'null';
                }
                // Compare the program category name with the selected option name
                return option.name === program.program_category.name;
              });
            });
          });
        });

Should return only the programs with Children beneficiaries but currently it returns the whole PDO object.
