Custom Field won't show up in future months....

[lookeruserjy]

hello - I set up a custom field as a measure, and I attempted to populate it for all months in 2020, but it will only populate for values up until the current month, which is May.

For example, if I inputted Revenue Forecast month for 2020, and I want these to plot as a dot in visualization, it’s only plotting up until May 2020. How do I get these to show for future months?
