Many false positives when scanning a Joomla latest 3.9.16 Stable

[vijaysar]

I have tried few times to scan the latest Joomla default install. This seems to be not working. The version shows as 1.5 and just lists the vulnerabilities in there, but all the vuls reported are false positives. Am I missing something in the setup
