The last two text fields you see below the email address field on the LP are probably the ones that you've added in the form. I think you'd have added the apt hint text for the other fields in the form (i.e., in the First Name, Last Name, Company, and Email fields), but it probably isn't added for the newer text fields. You'd want to add the hint text (placeholder text) to the new fields, approve the form and the LP and then check the LP. If that doesn't fix the issue, you can share the form editor snapshot and the LP URL, so we can have a look.
