MacVimSpeak does not seem to recognize any commands?

[dutchsparks]

MacVimSpeak does not seem to recognize any commands for me.
I tried in sublime text with vintage mode as well as the terminal with Vim.

When I start MacVimSpeak and click "start listening" the box becomes green and the built in microphone of Mac becomes visible.

But MacVimSpeak does not seem to recognize any commands.
For example,
when I press 10k manually, the cursor moves up 10 lines as it is supposed to.
but when I say "ten up", the mac microphone image is moving when I talk, indicating that it hears me speak. But the command does not appear in the small white box in the MacVimSpeak application and the cursor does not move up.

any ideas what might be going on ?

I presume you targeted the window that you want to enter MacVimSpeak commands into?

Secondly what version of MacOs are you running?
