I'm using the Select widget - Select by attributes - in an app and the Clear selection and Clear all functions do not actually clear values once they are entered in the attribute fields. These functions simply turn off the active selection, which can be done by simply unchecking the activate button. Any values entered have to be manually removed by the user. Honestly, I'm not sure what the purpose of the Clear selection and Clear all options if they do not actually clear out the selection fields.
Even more problematic, values entered for Date fields do not clear at all. Nothing I try will zero out these values once they are entered, except refreshing the entire application. That is not at all optimal for users to have to refresh the app every time they want to select by a date or date range.
