nvim: omni-completion with C-x C-o results in extra braces '[['

[khauchy]

I installed the latest Marksman (1.0.0-7f3b471) using snap and use it with nvim.

When I try to insert a wiki-style link, the completion inserts an extraneous [[. For instance:

• when I input [[<C-x><C-o>, the resulting link is [[[[file
• when I input [](/<C-x><C-o>, the result is [](/[](/path/to/file).

Have I made a misconfiguration in my configuration, or maybe I am using marksman wrongly?

My nvim version is as follows, and I've also included the minimalist init.vim I use below.
