Psychometric Chart Preview "off" not hiding mesh

Hello,

I’m unable to turn off the psychometric chart mesh and only preview the graph axis elements. Can you tell me why, when I turn off the “preview”, the colored mesh doesn’t disappear? I’ve also attached my file.

Thanks in advance,

You have to turn off the preview of custom previews that are connected to the outputs too.
