It is likely just a DIAGNOSTIC, which warns you of a potential problem. If you have addressed the issue, it will not go away, but you can ignore it and go ahead and file.

Why won't my diagnostic disappear?
Not all diagnostics will apply to your client's return, some are more informational than actionable (even if they are listed as Critical). Review the diagnostic and verify if the information provided is actionable to your clients return. If so, correct the return as needed. If not, check the "Ignore" box to mark it as complete.
Answers are easy. Questions are hard!
