What happens next
HPD treats the violation as uncorrected. On hazardous classes, enforcement statuses commonly follow if nothing else changes.
What to do
Make sure the condition is actually corrected before you certify again: a second invalid certification looks worse on the same file. Include documentation when you refile.
If this is on a building you own or manage, you file with HPD directly. We report what the city publishes; we do not file for anyone. Look up your own building.
If it is on your building and you would rather hand it off, ask to be introduced to one firm that files it.

If you rent here
HPD found that the certification the owner filed did not match what an inspector saw on a return visit. The violation is still open; call 311 if the condition is still there.

What makes a certification invalid rather than defective?
Defect Letter Issued marks a paperwork failure. Invalid Certification includes certifications a reinspection contradicted: the inspector found the condition still there.
Why would HPD find a certification invalid?
Invalid is what a reinspection finds when an inspector goes back and the cited condition is still there. That is different from paperwork HPD finds insufficient. A guide sets the two side by side, with what else can happen after you file. What happens after you file.
