Peekabo window Mark not in markbar

[matko031]

When using select a mark functionality (as described here, I get a message saying Mark not in markbar: w (in case I did <leader>w). I can see the mark in the window and if just pressing the letter of the mark, vim takes me to that mark, so it's only the issue when wanting to show the mark in the peekabo window without actually going there.

I'm not able to reproduce this issue on my machine, unfortunately. Could you post more detailed reproduction steps (e.g. "in a blank file, set mark 'w'") and your configuration for the plugin?
