Custom left soft key label must be restored explicitly in WRT 1.1 (Browser 7.1) (Known Issue)
On WRT 1.1 (Browser 7.1) devices, it is possible to customize the left soft key's label and operation by calling window.menu.setLeftSoftkeyLabel(String label, Function callbackfunc). However, the default label is not restored automatically when the widget is closed and a new one is opened. Because of this, an unrelated text label may be shown instead of the Options text in the newly opened widget.
When you use custom labels in your widget, make sure that the default label is restored when the widget is closed. If you want to be sure that the default menu label is shown correctly in your widget, window.menu.setLeftSoftkeyLabel(´´, null); can be called on the startup.
This issue will be corrected in upcoming firmware updates.
