php type hinting creates invalid error in Dreaweaver CC 2020

public function addToValidators(array $data) : void;

^this is valid php, but creates a syntax error in Dreamweaver CC 2020. I am fully updated as of this posting. Using php 7.3 and Dreamweaver is set to 7.1. This is valid php per php 7.1. How do I fix this error? I do not want it showing up. I cannot find it in your source code.

You can do what I do, ignore it. Or disable Linting in your Preferences.

Thank you for your reply. I do not want to ignore it. This is a paid service. What does linting have to do with PHP? When I toggle that setting it is only css/html.  Do you know the location of the php errors in the DW CC source code? That would be a solution.

I see one was already logged a while back about something similar.
