Query Record Type filter issue

Hi Team,

I have written query record type with filters to get the records which are reviewed one year back. Filtering based on field "reviewedOn".
Currently when i am testing this rule, getting records those have "reviewedOn" is null. How to eliminate these records which have "reviewedOn" is null.
Attached Query and output for your reference:
Please suggest if any solution available to fix this.

a!localVariables(
  local!lastOneYearReviewedAttestations: index(
    a!queryRecordType(
      recordType: 'recordType!{7e2fbae0-0b6b-4c59-9981-8ea4fef6165c}Attestation',
      filters: a!queryLogicalExpression(
        operator: "AND",
        filters: {
          a!queryFilter(
