Why can't I hide piping hidden lines with a config.pro anymore?

I can no longer find the config.pro option "hlr_for_pipe_solid_cl"

I have been using this option to hide the hidden center lines in parts created using piping on drawings. Today I suddenly can no longer find this config.pro option I've been using for months!!

Does anyone have another workaround for this issue? I feel like all I ever do in Creo 3.0 is workarounds.

Is PTC making changes?? I am so confused!
