No Filtering Keyword _nf issues/questions

[jbk68]

I currently have a grid with 10 columns of which I have used the keyword _nf to not allow 4 of these fields to be shown when a user presses Knack's "Add Filter" button to filter data. Works great until user presses the "Add Filter" found on the open filtered window to add additional filters at which time ALL 10 fields are shown in the 2nd level of filtering.

Didn't know if there was a fix or alternative filter for this.

Thanks... JON
