There are three different problems here:

1. 'multiple' => 0, declaration is causing the "Array" output. Select field is by default non-multiple, so please remove this declaration.

2. fixes #1892, fixes #1888 #1901 should fix the problem with registered value not showing up with non-multiple selects inside repeaters.

3. Additionally you have "sidebar" and "footer" defined as defaults of widget_location however they are called "option-sidebar" and "option-footer" under choices.
