Too many results returned, fails to show there are vulnerabilities

[ghost]

Given a site "www.notrealsite.com" with header: X-Powered-By: PHP/5.3.3

The extension outputs:
[Vulners] start check for domain www.notrealsite.com for software PHP, headers/5.3.3 : https://vulners.com/api/v3/burp/software/?software=cpe%3A%2Fa%3Aphp%3Aphp&version=5.3.3&type=cpe
But does not report anything in Burp.

Opening this URL manually:
https://vulners.com/api/v3/burp/software/?software=cpe%3A%2Fa%3Aphp%3Aphp&version=5.3.3&type=cpe

returns this:
{
"result": "warning",
"data": {
"warning": "Too much results - 70 for the query (cpe:"cpe:/a:php:php" AND (cpe:5.3.3* OR (description:"5.3.3" AND NOT ("before version 5.3.3" OR "< 5.3.3" OR "less than 5.3.3" OR "before 5.3.3" OR "prior to 5.3.3")))) OR (description:"php" AND description:"5.3.3" AND title:"php" AND bulletinFamily:exploit AND NOT ("before version 5.3.3" OR "< 5.3.3" OR "less than 5.3.3" OR "before 5.3.3" OR "prior to 5.3.3") AND -type:seebug) with software:cpe:/a:php:php version:5.3.3",
"errorCode": 402
}
}
