Class SVF ERROR: Class not defined


I am using SuperCollider 3.12.0 on Win10.

I cannot find the class called SVF (State Variable Filter) UGens>Filters>SVF though I am sure that this class exists and it can be found on the documentation online. This class SVF cannot be found on the help browser inside my SuperCollider either, and UGens Filters are only 65 on my computer while there are said to be 117 Filters in total UGens>Filters.

As a beginner I have no idea at all what is going on! Desperately need your help! Thanks in advance :(((

P.s. I simply ran the example code from the documentation
