I can reproduce this using xenial 16.04 with the german translation.
Reproduction steps:
* Execute "unity-control-center keyboard shortcuts" in a terminal.
* In the left menu select "own shortcuts" (or equivalent translation).
* Press the + to add a new shortcut. Name it "Test" and ad some valid command like "unity-control-center"
* Select your new entry
What happens: The edit menu opens to edit the name and command
What should happen: The design changes indicating that the shortcut is recorded.
Please note: This works fine with the predefined shortcuts in "unity-control-center keyboard shortcuts".
