'ArcGIS Online dynamic text showing formular on load

I have created two indicators in an ArcGIS Online Experience app which show dynamic content from a data source. They are simple COUNT{FIELDNAME} and SUM{FIELDNAME} functions. When the app is loading, the formular is shown until the datasource delivers the result which is large and ugly. (see Screenshot)

How can I turn this off until the result is loaded?
