In general, it is rare that you don't want both outputs of the snapper going into your geometry building. I'd try ensuring you run the untouched and the snapped together. Check what you've got coming out of each stage by using the partial runs of FME 2018.x - you'll see what linework you have then at each stage and this should help.

Do you have some sample data? Take also a look at the GeometryCoercer transformer.
