How to remove non-existed blog from Ghost Desktop

I have played with local ghost in container and added it to Ghost Desktop client.
After some experiments I have removed container.
As result - I’m not able to remove this instance from Desktop application:
when I click on “Remove” item in context menu - just nothing happens.
When I try to edit - it claims “We cann’t reach the given URL…”

Also, while ghost desktop is starting, follow notification appears:

Is it possible to remove it somehow?

My OS: Linux Mint 19.1 Cinnamon
Ghost version (from log): 1.7.0
