I'm trying to convert a character made with classic C4d material into Octane ones , and I've troubles with hair (I've troubles with everything as I'm new

the hair guides are always displayed even if the hair object are desactivated ( looks like a refreshment problem too ? )
When hair is activated , it seems to works and display the hair polygons ( but still display the guides .. I can't find how to 'hide those guides ' )
have you any idea for this display problem ?
thx
