[asterisk-gui] can't create another dialplan

[dima]

Hello, everyone
I'm having a problem with adding another dialplan. On the "Calling
Rules" page I press the "New" button, enter the dialplan name and press
save. A gui_alert message appears "Sorry, an entry named
numberplan-custom-2 already exists!". numberplan-custom-2 does exist.
Even numberplan-custom-3 does. It looks like now my GUI keeps choosing
"numberplan-custom-2" as a name for any new dialplan context.
GUI is at 1301 revision.
Please, help me resolve this.

P.S. This is the end of my extensions.conf
