YouCompleteMe - Path of file

I would like to know settings that disable showing the path after dash. It is disturbing and not necessary.

I tried to search on google on YouCompleteMe doc, but unsuccessful. I have no idea which keywords to use. And also I tried to find in vim

:help ycm

but also not successful.

I provided an output of auto-completion that shows the paths. Thank you for any ideas.

I wrote this question because google failed me (or I failed google that?).
