User Filters (change 'Unknown')

User Filters (change 'Unknown')

Hi Team,

I have a user filter at the top of my dashboard. The filter is referencing a column that has three values (Yes, No, and blank value). The blank value is actually empty not text saying blank value.

The user filter provides a choice of Yes, No, and Unknown. How can I change the user filter from Unknown to say 'Not yet filled in', or Blank?

The word Unknown is confusing and reduces the users trust in the data.

Thanks

Steve
