Node edit form keeps toggle on when custom path is provided

Problem/Motivation

I have a node with Title Home, an automatic Alias woud be /home, but i Prefer /home-sn to keep all my domain home pages easy to lookup in /content. So I add a /home-sn alias for my domain (Senegal) and uncheck: Generate automatic URL alias for .sn. I save the node and the path is generated and everything checks out.

Now I come back later and want to edit the page. Now the Generate automatic URL alias for .sn is checked while I have provided a custom path. On save, it is overwritten (You don't check something that is already properly configured) as the checkbox is default true. There goes my 'custom' path.
