New Burp 2.0+ XssValidator doesn't work the same..

[Nullifidian]

I've tested this on 3 different computers, and when I'm using newer versions of Burp (2.0+) XssValidator has a significantly high false positive rate (co-workers say the same thing). When I install an older version (v1.7.37 or older) it has like a 95% success rate? is it time for an update? or should I stick to using the older burp for this one tool?
