I am unable to remove the Prefix and subtitle boxes from the submissions page 3. Enter Metadata

I have seen the previous answers at this link https://forum.pkp.sfu.ca/t/how-to-remove-prefix-and-subtitle-fields-from-article-submission-enter-metadata-step-3/41256.

But the file doesn’t contain the fields mentioned.

Please help me to remove those fields.

I am using the latest version of OJS 3.2.0-1
