In ArcGIS Web AppBuilder, when using the Select widget, if one of the feature layers included in the widget has a name that exceeds the default width of the widget pop-up, the selected feature count becomes obscured.

Workaround

Depending on the theme and the placement of the widget (inside or outside of a widget controller), it will display as a sidebar or a pop-up. The sidebar cannot be resized, but the width of the pop-up window can be adjusted to display the feature count and the full layer name.
