False positive vulnerable items reopened

[chandukollapart]

Hi,

I have questions regarding the false positive vulnerabilities. Please see below

1) Does false positive vulnerabilities reopened from source scanners (Qualys, Rapid7)? 

2) Once vulnerabilities are marked as false positive what are the options to reopen (Manually click on reopen?)?

Thanks in advance!

Also when I read the document it says "A false positive without an Until date is a permanent false positive". In that case even scanner shouldn't open the vulnerabilities right? Please let me know.
