Default [Q] edit widget settings

About the settings of widgets.

I use Calengoo calendar and this has a widget, on the widget settings you can alter the transparency.
You can change these settings when adding the widget to a screen but on my previous htc one I could alter them after the widget was put on a screen.
Long pressing the widget gave me the opportunity to delete or edit it.
On the xperia z1c I can only see the garbage can when long pressing the widget, I do not have the opportunity to change the widget.
Is this normal or is there a possibility to edit the widget after installation?
