preview is not scrolling to the concerned line in the file

[akabakass]

vim --version:

VIM - Vi IMproved 8.2 (2019 Dec 12, compilé Jan 08 2021 14:00:27)
Rustines incluses : 1-2311

config used:

let g:quickr_preview_keymaps = 0
let g:quickr_preview_position = 'above'
let g:quickr_preview_on_cursor = 1
let g:quickr_preview_exit_on_enter = 1

When I use :ltag <tagname> followed by :lopen, the preview always shown the begining of the file, but if press enter on a result, It jumps to the good line in the file.
I'm not sure my explanation is really clear, so feel free to ask if more clarity is needed.
