When labeling some of the widgets you are “allowed” space for several characters.
However, when you save and view the widget, depending on how many characters your label is, may be truncated by the physical size of the displayed widget.
One easy widget to view this issue would be to assign a label of more than 6 characters to the LED Widget and you will see the issue.
Suggestion is to allow for resizing of the widgets or limit the allowed label size (less desirable option for sure).
I have room for at least 8 characters on my tablet. If I could put in more characters and it overflowed the LED widget, then I would reduce the number of characters to make it fit.
