When you use the FilteredTextBox with the FilterType "Numbers" and enter one of the special characters .'!"#%&(@£$€|{[]}~\ it will show up in the TextBox for a very short moment and then disappear, wheras regular characters (a-z, A-Z) and the special characters ;,:*^`´¤/)=?+<>½§ do not behave in this anomalous way. If you have some text selected in the text box when you enter one of these "anomalous" characters, the text will disappear, wheras this will not happen with the other characters. In addition, undo (ctrl-Z, alt-backspace) will not work in this case.
